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?”

Question

A person working out, with arms stretched out to either side, holds 5 kg in each hand. While
sitting on a spinning stool, he is spun around by a helpful friend. What will happen to his
angular speed, if anything, when he lets the weights fall to the floor? Explain in detail your
answer.

To promote his new single “Itaktak Mo”, Joe decided to launch a satellite into orbit that will intercept allairwaves and play his song worldwide. To do this, he needs to mount his 100 [kg] satellite onto a 750 [kg]rocket. It blasts off vertically from a launch pad with a constant net upward acceleration of 3.80 [m/s2].When it has reached a height of 680 [m], the satellite was released, and the rocket blew up shortly after,due to a system failure. Assume that the satellite was not damaged after the explosion. A. What is the maximum height that the satellite will reach above the launch pad? B. How much time will elapse after system failure before the satellite comes crashing down the launchpad? C. How fast will the satellite be moving just before it crashes?

Three identical small spheres, each of weight 2 lb, can slide freely on a horizontal frictionless surface. Spheres B and C are connected by a light rod and are at rest in the position shown when sphere B is struck squarely by sphere A which is moving to the right with a velocity v0 = (8 ft/s)i. Knowing that θ= 45° and that the velocities of spheres A and B immediately after the impact are vA = 0 and vB = (6 ft/s)i + (vB)yj, determine (vB)y and the velocity of C immediately after impact.
