Given : top of a tower a ball is thrown vertically upwards with an initial velocity U write expressions for
To Find : (a) velocity (b) height above the tower of the ball at time
Solution:
Initial Velocity = U
V = u + at
a = - g ( acceleration due to gravity )
V = U - gt
velocity = U - gt
S = ut + (1/2)at²
h = Ut -(1/2)gt²
height above the tower of the ball at time = Ut -(1/2)gt²
