A body of mass 500 g is at rest on a frictionless surface. Calculate the distance travelled by it in 10 second when acted upon by a force of 10-2 N.


Force = 10-2 N = 0.01 N initial velocity, u = 0
mass, m = 500 g = 0.5 kg distance travelled, s =?
time, t = 10 sec
Force = mass acceleration
acceleration, a = = = 0.02 m/s2

Using the equation, s = ut + at2


s = 010 + 2 = 1 metre
