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?”

A block with a mass of m=21 kg rests on a frictionless surface and is subject to two forces acting on it. The first force is directed in the negative x direction with a magnitude of F1. The second has a magnitude of F2 and acts on the body at an angle 0=18 degrees measured from horizontal. Write an expression for the magnitude of the normal force, FN acting on the block, in terms if F2 and the other variables of the problem. Assume that the surface it rests on is rigid. The two forces change such that F1=8.5N and F2=19N. Based on this change, the block may no longer be in static equilibrium. Find the blocks acceleration in the x direction, ax, in meters per second squared.

Sharon pushes a tall box across the floor. Her arms (and therefore her push force) of F = 400 N make a theta= 30 degree angle with the horizontal. Since the box rests on ball bearings it is essentially frictionless. Sick of her job, Sharon decides to give the box a brief shove lasting only t = 0.2 seconds. Find the velocity (magnitude and direction) of the box at the completion of Sharon's shove, assuming (a) the box's weight is 490 N, and (b) the box's weight is 122.5 N. In both cases, the box starts from rest.
