A radar station detects an airplane at a position 150 km and 35deg from the radar base. After 3 minutes have elapsed, the plane is at 200km, 150deg north from the radar base. Find the average velocity of the airplane in km/s.
|
150km²+200km²=d²
22500km+40000km=d² 62500km=d² 250km=d v=∆d/∆t v=250km/3min v=250km/180s v=1.39 km/s north |

Ronny goes to the market. he goes 120km, 50deg south from his home. after 2 minutes, Ronny is 220 km, 140 deg from his home. find the average velocity of Ronny in km/s.
|
120km²+220km²=d²
14400km+48400km=d² 62800km=d² 250.59km=d v=∆d/∆t v=250.59km/2min v=250.59km/120s v=2.09 km/s south |

|
Alan rides a scooter from his school. He goes south at 20m/s and west at 15 m/s. What is his relative velocity to his friend waiting at school?
|
15m²+20m²=c²
225m+400m=c² 625m=c² 25m/s=c v=25 m/s southwest. |
|
|
James is walking through the park. He goes 60 m/s east and 50 m/s south. What is his relative velocity to the bench he started walking from?
|
60m²+50m²=c²
3600m+2500m=c² 6100m=c² 78.10 m/s=c v=78.10 m/s southeast |
