Answer 1

A BodY that a body is moving with a velocity of 12 metre per second and it comes to rest in 18 metre per second what was acceleration

Answer 2

Hey Mate

Your answer is here

Initial velocity (u) = 12 m/sec.

Final velocity (v) = 0

Covered distance (s) = 18 m

Let acceleration of body = a m/sec^2

Then according to third equation of motion

v^2 = u^2 + 2as

12×12 = 2×a×18

a = 4 m/sec^2.
