Answer to Question #40956 in Mechanics | Relativity for alzahra

Question

A boy standing still throws a ball at an angle 600, with the horizontal as shown in the
figure below. At the moment the boy releases the ball, he ran eastwards to catch the ball.
If the boy caught the ball in exactly 2 seconds at the same height from which he threw it.
Neglect the effect of air resistance or wind on the ball.

a) What is the magnitude of the initial velocity, |v0|, with which the boy threw the ball?

b)With what average velocity (magnitude and direction) must the boy run in order to
catch ball at the point shown?

c) What is the speed of the ball when the boy catches it?
