A ball is fired from point `P`, with an initial speed of `50 m s^-1` at an angle of `53^@`, with the horizontal. At the same time, a long wall `AB at 200 m` from point `P` starts moving toward `P` with a constant speed of `10 m s^-1`. Find
(a) the time when the ball collides with wall `AB`.
(b) the coordinate of point `C`, where the ball xollides, taking point `P` as origin.
.

A paricle is projected from a point with initial speed of 10 m//sec at an angle of 37^(@) with the horizontal. At the same instant a fly starts on the same path of particle with constant speed of 10 m//s Then :
