Question

A small ball is shot vertically upward from the top of a building 25 m above ground
with initial velocity 9.81 m/sec. Determine the maximum height the ball will reach.​

Answer 1

Answer:

u=9.8m/s

a=-9.8m/s²

v=0

s=?

v²=u² + 2as

0 = (9.8)² -2(9.8)s

0= 9.8 -2s

4.9 = s

the ball will go 4.9 m above the building or 29.9m above the ground
