Textbook Question

Chapter 2, Problem 52TAS

A force Facts in the forward direction on a cart of mass m. A friction force f opposes this motion.

(a) Use Newton's second law and show that the acceleration of the cart is- F − f m .

(b) Show that if the cart’s mass is 4.0 kg, the applied force is 12.0 N, and the friction force is 6.0 N, the cart's acceleration is 1.5 m/s².
