3. A heavy machine is being lifted from the ground up a building using a set of pulleys with rope. The end of the rope moves at 5m/sec and the machine rises at 1 m/sec. The end of the rope is attached to a hoist mounted at the ground. 3.1. As the machine slowly lifts off the ground, the tension on the rope near the hoist is 1000 N, what is the weight of the machine? 3.2. As the machine being lifted, the rope near the hoist snapped, sending it falling to the ground. How much is the acceleration of the rope at the snapped end?
