a 38 N horizontal force pushes on a 3.7 Kg mass resting on a horizonal surface. The surface exerts a friction of 22 N against the motion. The acceleration of the 3.7 kg Mass is
Homework Answers
According to Newton's Second law of motion:
Since friction is an opposing force we have Fnet =38 - 22 = 16 N
Given mass = 3.7 kg, then acceleration is given by:
