1. To move a 45 kg wooden crate across a wooden floor ( = 0.20), you tie a rope onto the crate and pull on the rope. While you are pulling the rope with a force of 115 N, it makes an angle of 30 * with the horizontal. a) How much time elapses between the time at which the crate just starts to move and the time at which you are pulling it with a velocity of 1.4 m/s? b) Draw a free body diagram 2. A 549 N woman is standing on a scale in an elevator that is going down at a constant velocity. Then, the elevator begins to slow and eventually comes to a stop. The magnitude of acceleration is 0.73 m/s?. a) What is the direction of the acceleration? b) What is the reading on the scale while the elevator is accelerating
