Question

A stone falls from the top of a building and hits the ground at a speed of 32m/s. The air resistance-force on the stone is very small and may be neglected.
Calculate the time to fall.

Answer 1

Thanks for asking the question.
Given data is:
u=0m/s
v=32m/s
a=g=9.8m/s2
According to the first equation of motion,
v=u+a*t
32=9.8*t
32/9.8=t
t=3.265sec
The final answer is 3.265s.
Hope it helps.
