The initial velocity of a body moving along a straight lines is `7m//s`. It has a uniform acceleration of `4 m//s^(2)` the distance covered by the body in the `5^(th)` second of its motion is-

A

25m

B

35m

C

50m

D

85m

Text Solution

Verified by Experts

The correct Answer is:
A
Distance covered in nth second –
`S_n = u = a/2 (2n - 1)`
`rArr S_5 = 7 + 4/2 (10- 1) = 25m`
