A boy travelling in an open car moving on a levelled road with constant speed tosses a ball vetically up in the air and catches it back. Shetch the motion of the ball as observed by a boy stanceing on the footpath. Give explanation to support your diagream.

Text Solution

Verified by Experts

For a ground observer, the ball is a projectile with speed (u) making an angle of projection ` theta` the horizontal direction as shown in Fig. 2 (RP). 19 (b). The ball will follow a parabolic path . Fig. 2 (EP). 19 (a)

A base ball player has a nightmare. He is accidentally locked in a railroad boxcar. Fortunately, he has his ball and bat along. To start the car moving, he stands at one end bats the ball towards the other end. The impulse exerted by the ball as it hits the end wall, gives the car a forward motion. Sice the ball always rebounds and rolls along the floor back to him, the player repeats this process over and over. Eventually the car attains a very high speed, and the player is killed as the boxcar collides with another car sitting at rest on the track. Analyze this dream and the physics concepts involved in it.
