Question 1

Part a) Two objects are connected by a light string passing over a light, frictionless pulley as shown in the figure below. The object of mass m1 = 6.40 kg is released from rest at a height h = 3.20 m above the table. Find the maximum height above the table to which the 3.00–kg object rises.

Part b)A smooth circular hoop with a radius of 0.900 m is placed flat on the floor. A 0.375-kg particle slides around the inside edge of the hoop. The particle is given an initial speed of 8.50 m/s. After one revolution, its speed has dropped to 5.50 m/s because of friction with the floor.What is the total number of revolutions the particle makes before stopping? Assume the friction force remains constant during the entire motion.
