Question

A 20 kg box is pushed across a carpeted floor with an applied force of 65 N. The friction acting against the box has a force of 23 N. What is the acceleration of the box?

Answer 1

Use the formula F=ma

Force is going to be 88, because the frictional force acting against it increases the force. So we need to add the frictional and applied force together.

f= 88

m= 20

a=?

F=ma

88=20 x a

88/20 = a

a= 4.4 m/s^2
