A body falls from rest in the gravitational field of the earth. The distance travelled in the fifth second of its motion is `(g = 10m//s^(2))`

A

25m

B

45m

C

90m

D

125m

Text Solution

Verified by Experts

The correct Answer is:
B
Distance travelled in nth second
`S_n = u + a/2 (2n - 1)`
`S_5 = 10/2 (5 xx 2-1) = 45m`
