Two blocks connected by a light horizontal rope sit at rest on a horizontal, frictionless surface. Block A has a mass of 18 kg and Block B has mass m. A constant horizontal force F= 75 N is applied to Block A. In the first 3.0 seconds after the force is applied, block A moves 15 m to the right.1. Write Newton's second law for block A along the horizontal direction and solve for the force exerted by the rope on block A.2. Write Newton's second law for block B along the horizontal direction and solve for itss unknown mass m. ( F rope on A = F rope on B)

A cardboard box rests on the floor of an elevator. The box has a mass m = 2.75 kg and the elevator has an upward acceleration of a. a. Write an expression for the sum of the forces acting on the box in the y-direction, ΣFy, given that up is the positive y-direction. Your answer should be in terms of FN, m, and g. b. Write an expression for the normal force, FN, that the block experiences in terms of the elevator's acceleration, the block's mass, and the acceleration of gravity. c. If the elevator's acceleration has a magnitude of g in the downward direction, what would the normal force, FN1 be in Newtons? d.If the elevator's acceleration had a magnitude of g in the upward direction, what would the normal force FN2 be in Newtons?
