The diagram shows a glider travelling on a friction-free linear air track.
air from a pump
Which one of the following graphs best represents the variation of velocity with time as the glider bounces back and forth between the elastic buffers?
The diagrams show the direction and speed u of a ball before it strikes a vertical wall and its direction and speed v after striking the wall. wall wall u v
The ball is in contact with the wall for a time ∆t.
The magnitude of the average force F exerted on the ball by the wall is given by mu − mv
F = ( mu − mv ) ∆t .
F = ( mu + mv ) ∆t .
mu + mv
A particle of mass m moves with constant speed v in a circle of radius r. The work done on the particle by the centripetal force in one complete revolution is
2π m v 2 .
A block of mass M is pushed along a horizontal, frictionless
