A body falls from a height of 500 m. In how much time, will it strike the ground ? (Give the answer in seconds)
Here,
Initial velocity, u = 0
Distance covered, S = 500m
Acceleration due to gravity, g=10ms−2
Step 1: Time taken:
From 2nd equation of motion,
s=ut+12at2⟹500=0+12×10×t2
t2=5005
t2=100
t=10s
Hence, it will strike the ground, after
t=10s
