Pull
friction
A basket of apples is pulled with a constant force. A friction force acts in a direction opposite to the motion. The basket starts at rest and
increases its speed over time. Choose three actions that will REDUCE the rate at which the speed of the basket changes.
Pull with less force
Pull with more force
Add an apple to the basket
Take an apple out of the basket
Smooth the surface of the table to decrease friction
Roughen the surface of the table to increase friction
