1. In physics class, a friction box slides across the table with an applied force of 20N. The students measure the net force to be 14N. What must the frictional force acting on the block be?

2. In physics class, students roll a toy car across the table. The toy car has a mass of 3kg. The students apply a force of 10N to the car and friction holds it back with 1N of force. What is the acceleration of the car?
