Question

part a
when youre driving on the highway its necessary to keep your foot on the accelerator to keep the car moving at a constant speed. in this situation

• the net force on the car depends on your speed.
• the net force on the car is in the forward direction.
• the net force on the car is zero.
• the net force on the car is toward the rear.

Explanation:

According to Newton's first law, an object moving at constant velocity has zero net force. The car maintains constant speed, so acceleration is zero, hence net force is zero.

Answer:

the net force on the car is zero.
