1. A bucket of mass 4.03 kg is pulled by a rope and accelerated straight upwards at a rate of 1.62 m/s2. What is the tension in the rope? Express your answer in Newtons.
2. Two masses are connected by a light string and pulley as shown below. The mass on the left is 2.34 kg and the mass on the right is 3.60 kg. The system is released from rest. If the heavier mass starts at a height of 1.51 m above the ground, at what time will it strike the ground? Express your answer in seconds.
