A boy throws a ball with initial velocity `u` at an angle of projection `theta` from a tower of height H.
Neglecting air resistance, find
a. How high above the building the ball rises
b. Its speed just before it hits the ground.

A ball is dropped from a height h above ground,Neglect the air resistance,its velocity (v) varies with its height y above the ground as

Three identical balls are thrown from the top of a building, all with the same initial speed. As shown in figure., the first ball is thrown horizontally, second above horizontal level, and third at an angle below the horizontal. Neglecting air resistance, rank the speeds of the balls at the instant each hits the ground.

A boy throws a ball with a velocity u at an angle theta with the horizontal. At the same instant he starts running with uniform velocity to catch the ball before it hits the ground. To achieve this he should run with a velocity of
