Question

Starting from rest,an object moves along a straight path with uniform acceleration.After 5s its velocity becomes 20m/s.Find the acceleration of the object

Answer 1

Explanation:

a = (v-u) /t

a = 20-0/5

a= 4 m/s²

Answer 2

Answer:

-4m/s

Explanation:

because the formula for acceleration is v-u/t where v=initial velocity ,u=final velocity and t= time
