Question

The velocity of a moving object change from 20m/s in 10 seconds calculate its acceleration

Answer 1

here.

initial velocity = u = o

final velocity = v = 20

time taken = t = 10

acceleration = u- v /t

acceleration = 20 - 0/10

acceleration = 20 / 10

acceleration = 2

the acceleration of given example is 2 m/s2
