Question

a boy travelling in an open car moving on a levelled road with constant speed tosses a ball vertically up in the air and catch it back sketch the motion of the ball as observed by a boy standing on the foot path give explanation to support your answer​

Answer 1

Explanation:

With respect to the observer standing on the footpath ball is thrown with velocity u at an angle θ with the horizontal, hence it seems as a projectile. So path of the ball will be parabolic. The horizontal speed of the ball is same as that of the car, therefore, ball as well car travels equal horizontal ult distance. Due to its vertical speed, the ball follows a parabolic path.

Important point: We must be very clear that we are working with respect to ground. When we observe with respect to the car, motion will be along vertical direction only.
