Question

A body initially at rest starts moving with a constant acceleration 2m/s calculate the velocity acquired

Answer 1

here the given data are

initial veleocity (u) = 0

acceleration (a)  = 2m/s2

time taken = 1 sec

by the relation we know that 

v = u+at

v = 0 + 2 × 1

v = 2m/s

therefore the velocity is 2 m/s

Answer 2

therefore velocity is 2m/s.
