Question

1a) The magnet's mass is 5.83 kg and the magnetic force pulling it to the right is 121.7 N. The length of the cord is 1.72 m, and the ceiling is 3.35 m above the floor. Suppose that you cut the cord and the magnet falls to the floor while still being pulled to the right by the force of 121.7 N. How long will it take the magnet to hit the floor?

1b) the magnet has mass 5.77 kg, the force pulling it to the right is 187.6 N, the cord has length 1.77 m and the ceiling is 2.89 m above the floor. How far to the right of its start point will the magnet have traveled when it hits the floor after the cord is cut?
