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.

Two masses are connected by a massless string, passing over a massless, frictionless pulley as shown in the diagram. Mass m1 = 5 kg, and is released from rest at a height h = 4 m above the table. Mass m2 = 3 kg, and starts at rest on the table. Ignore friction and air resistance. Take the system to be the two masses and the earth. What is the potential energy of this system, in Joules? Next, you let...

Two objects are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below. Two objects, labeled m1 and m2, are connected to a rope which is hung over a pulley connected to the ceiling. The pulley is of mass M and radius R. An object labeled m1 hangs suspended off the surface on the left side of the pulley. An object m2 is on the right side of...

Two blocks are connected by a string that passes over a massless, frictionless pulley, as shown in the figure. Block A, with a mass mA = 2.00 kg, rests on a ramp measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs vertically below the pulley. Note that you can solve this exercise entirely using forces and the constant-acceleration equations, but see if you can apply energy ideas instead. Use g = 10 m/s2. When the system is released...
