The objective of this lab was to figure out how to determine the range from a given set of velocity and height from the ball.
The height of the ball when it leaves the horizontal projectile is at 93.5cm or .935m. The velocity of the ball was .0674 seconds in the range of .1 meter. Creating a total velocity of 1.484m/s. To calculate the hang-time the formula: y= -4.9t^2 was used. The hang time is used to figure out how long the ball will be in the air for. After you find the answer, the time is then multiplied by the velocity to get the range.

The horizontal velocity does not affect the hang time because in the equation to figure out the hang time y= -4.9t^2, there is no variable for velocity. The horizontal does affect the range because to calculate the range with the equation of x= Vxt, the variable for velocity is present. The lab showed that the horizontal and vertical motion are completely independent from looking at the velocities of both. The horizontal velocity never changed; it was constant and cannot be changed by the height, whereas the vertical velocity can be. Depending on the height the velocity is changing constantly because of the hang-time. In conclusion, the two velocities are independent because they don’t affect one another or that they don’t get affected by the same variable. …show more content…

    Equally, a reading of 1.00m was obtained when measured on the short range setting (Table 1). The percentage deviation was negligible, at 0 %. A correction factor was applied while calculating the subsequent 1-m distances that were used to compute the range of the motion sensor. This ruled out any possibilities of discrepancies, suggesting that the experiment was conducted with a high degree of precision and accuracy.…

    Record the height (Y_0) of the projectile and find the corresponding time of flight using the equation t=√(2Y_0)/9.8. Place the plastic ball into the launcher and use the push rod to load the ball until the “3rd click” is heard. Press the Start button on the Smart Timer and pull the launch cord. Record the horizontal distance (X) traveled by the projectile and the time from the Smart Timer. Repeat steps 2-4 five times.…

    Landing Point Lab Report

    The centre of where the bob lands is hard to find because you will get two maybe three indentations on the paper. This will make it hard to find the exact distance from where the bob is launched to where it lands. There when comparing the calculated result to the measured result is could cause a millimetre different between the two. (see figure 4) How the experiment was able to be undertaken…

    The highest with the faster speed and no slits was 9 inches, and the average height was 5.35±.67 inches. The highest with the slower speed and slits was 11inches, and the average height was 7.38±.88 inches. The highest with the faster speed and slits was 10 inches, and the average height was 5.69±.67 inches. The trials with the slower speeds both had higher averages and higher maximum s than the faster speeds’. The trial with the slower speed and no slits did have a larger maximum than that of the slower speed with slits, this could be due to the fact that the bowl might not have been perfectly balanced and not directly in the center.…

    Relayed Throw Equation

    Baseball is a game of speed, despite not having a game clock, play clock, or any other sort of time constraints. The difference between being called out and safe can be determined by a fraction of a second. That call could be the difference between winning and losing a game. If you spend twenty minutes at any high school, collegiate, semi-pro, or professional baseball team’s facility, you will see coaches with stop watches timing players running, throwing, and transferring the ball. Coaches and players are constantly working on improving their times in order to execute defensive plays more efficiently, which will result in more put outs.…

    My Slapshot In Hockey

    Last Thursday, I had a hockey practice, and before anyone else came on the ice, my brother Michael and I were just shooting around. To see how fast my slapshot is, I had him stand at the other end of the ice, and using his phone, see how long it took for my shot to go from one goal line to the other, exactly 60.96 meters. Keeping the puck on the ice the whole time during my shot, changing just the position of the puck, my slapshot took 4 seconds to cross the far goal line, making my slapshot move at a velocity of 15.24 meters per second. This calculation was done by divided the total displacement by the total time, 60.98 meters divided by 4 seconds. Finding the velocity of the puck relates to what we are doing in class, as we are talking about…

    The documentary called “Hanging: the mysterious case of the boy in the barn” written by Julia Prodis Sulek touches base on a unique phenomenon that these parents known as the Klaver are facing with. A catastrophic incident has occurred almost twenty-five years ago, which involved a young child by the name of Joshua Klaver, who was fatally being lynched. Whether the death of Josh was simply a suicide or even a homicide, still remains to be a mystery. In this critical analysis, we will be breaking down layers of Julia’s perspective of the story and also the interviews that she has conducted. Critiques’ will appropriately be made if holes are found in her writing.…

    Softball Vs Baseball Essay

    Softball versus Baseball in Terms of Speed and Distance There has been, and will for a long time be, much controversy about whether or not baseball players are better, and the sport is more difficult, than softball. If you were to go to a baseball game and then go to a softball game, it would appear that the baseballs are hit harder and farther than the softballs were hit. The two specific fields even differ largely in dimensions: The baseball field being larger than the softball field. There are many things that may contribute to this, such as softball is generally played by females while baseball is generally played by males, the gender difference also means a difference in muscle and strength.…
