Newton's second law:
We'll also use the Kinematic equation:
Using Newton's second law equation:
F - f = ma
A 30.0 kg- box is being pulled across a carpeted floor by a horizontal force of 230 N, against a friction force of 210 N .
a. What is the acceleration of the box?
b. How far would the box move in 3 s, if it starts from rest?
