A small compact car is pushing a large van that has bro-ken down, and they travel along the road with equal velocities and accelerations. While the car is speeding up, is the force it exerts on the van larger than, smaller than, or the same magnitude as the force the van exerts on it? Which vehicle has the larger net force on it, or are the net forces the same? Explain.
Solution 32DQ The mass of the car is less than the van They are equal from newton’s third law Since F =ma While the car is speeding up, the force exerts on the van is same They have same or constant acceleration because change in velocity is zero The larger mass of van has largest net force
