Concept

Problem: 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?

FREE Expert Solution

Newton's second law:

ΣF=ma

We'll also use the Kinematic equation:

x=v0t+12at2

a.

Using Newton's second law equation:

F - f = ma
