Question

A stone is allowed to fall from top of tower 50m height. Calculate time and velocity taken by the stone to meet the earth. g=9.8m/sec

Answer 1

Answer:

Given,

H=50m

g=9.8m/sec

We have a formula i.e,

T^2=2H/g

T^2=2×50/9.8

T^2=1000/98

T=(10×5^1/2÷7)sec

T=u/g

u=T×g

u=(14×(5)^1/2)m/sec
