EXAMPLE 2.15
A boy throws a ball vertically up. It retu
the ground after 5 seconds. Find
(a) the maximum height reached by the ball.
(b) the velocity with which the ball is thrown up.
SOLUTION
Initial velocity (upward) V = ?
Gravitational acceleration g = – 10 ms?
Time for up and down motion to = 5 s
Velocity at maximum height Vi = 0
S= h = ?
Actually my question is that what do we mean by this to=5s ?
