Question

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​a body

Answer 1

Acceleration : Rate of change of velocity per unit time ..

change in velocity = (u2-u1)

= final velocity - initial velocity

u1 = 12m/s , u2=18m/s , t= 1 s

Acceleration = (u2-u1)/t

= (18- 12 )1

= 6 m/s² Ans
