Question

If an object accelerates from rest, with a constant acceleration of

Answer 1

The velocity of the body affter 2 seconds is 20 m/s

What is acceleration?

Acceleration, a is the change of velocity with time. this is represented mathematically as

a = ( v - u ) / t

where:

u = intial velocity

v = final velocity

t =  time

Given:

a = 10 m/s2

t = 2s

u = 0  ( from rest means initial velocity is zero )

therefore

a = v / t

v = a t

v = 10 * 2

v = 20 m/s
