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