Question

From the top of a building 100m in height a ball is dropped and
at the same time another ball is projected vertically upwards with
a velocity of 25m/s Find when and where the two balls will meet
(g=9 8m/s2)

Somnath physics · Accepted Answer

Height of the tower =
100m

g = 9 8
m/s2

velocity of projection of ground
projectile = 25 m/s

Velocity of projection of the
tower projectile = 0

Let the particles meet at time t
and at height h

Thus,
