Boxes A and B are in contact on a horizontal, frictionless surface. Box A has mass 20.0 kg and box B has mass 5.0 kg. A horizontal force of 100 N is exerted on box B. What is the magnitude of the force that box B exerts on box A

Sagot :

Answer:

80 N

Explanation:

For A + B: the net force is 100 N = (mA + mB)*a

a = 100/(20 + 5) = 100/25 = 4 m/s²

For A, the net force = mA * a = 20 * 4 = 80 N
