Question

1. What will happen if a car experiences a 300 N force to the right from the engine and a separate 150 N force due to friction and air resistance to the left? Show your work to support your position.

Answer 1

Given:

Force acting on the car moving it to the right = F1= 300 N

Force due to friction and air resistance moving it to the left = F2 = 150 N

To determine:

The net force on the car

Explanation:

Force is a vector. The force of friction acts in a direction opposite to the applied force.

If, F1 = 300N, right, then F2 = -150 N, left

Therefore, the net force acting on the car will be:

F = F1+F2 = 300 - 150 = 150 N

Ans: Since the force acting on the right is greater, the car will experience a net force of 150 N which will accelerate it to the right
