Q1: A car's engine exerts a force of 720 N to the right. What is the resultant force acting on the car if the friction force on the wheels is 125 N? Q2: Ahmad is pushing a 30 kg block across a horizontal marble floor at a constant speed of 1.0 mh The coefficient of kinetic friction is 0.15. How large is the force that Ahmad exerts on the block? Q3: Suppose this 18 kg bike is moving at a constant velocity. What is the value of the coefficient of kinetic friction if the friction force acting between the bike and the road is 31 N? Q4: A 1,250 kg car is moving due to 6,500 N engine force. If the kinetic friction coefficient between the car and the road is 0.32, what is the car's acceleration? **Please I need a surely answer and a quicker response**

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
