Question

a trolley of mass 20 kg was originally at rest on a smooth horizontal surface. by how much will it acceleration if a pulling force of 22 N is applied on it horizontally?

Answer 1

Answer:

We can solve this question using Newton's 2nd law ,

F = ma

22N = 20kg x a

22kgm/s^2 = 20 kg x a  (kgm/s^2 is another unit for force. 1 kgm/s^2 = 1N)

a x 20 kg = 22 kgm/s^2

a  =  $\frac{22kgm/s^2}{20kg}$

a  = 1.1 m/s^2
