At the start of a motion along a line the initial velocity is u and acceleration is at. The final velocity v after timet, is

A

v = u + at

B

`v = u + a t^(2)`

C

`v = u + (1)/(2) a t^(2)`

D

`v = a t^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Given, initial velocity, u = v
acceleration a = at
`therefore` Final velocity is `v = u + a t = u + (a t) xx t = u xx a t^(2)`
