Question

A body of mass 100 grams is at rest on the smooth surface a force of 0.2 Newton acts on acts on it for 5 seconds calculate the distance travelled from the body

Answer 1

mass of that body = 100g/1000 = 0.1 kg

Using: F = ma

0.2 N = 0.1 kg * acceleration

i.e. a = 2m/s²

Using equation of motion:

s=ut + ½at²

s= 0 + ½ 2 m/s² * (5 sec)² [u=0, as the body was in rest initially]

s = 25 m
