4. Blocks of masses 11.0 kg and 25.0 kg hang on opposite sides of a pulley (Atwood's machine) with a massless string that rotates the pulley without slippage. The mass of the pulley is 1.5 kg and it has a radius of 15.0 cm. The heavier mass is 2.5 m above the ground and the lighter mass is 1.2 m above the ground. Using energy consideration, determine the velocity of the two masses when the heavier mass hits the ground....

1. Two masses are connected with a rope via a pulley. Mass m1 is 4.00 kg and initially at rest on the floor. Mass m2 is 7.00 kg and initially is held at rest 2.00 m above the ground. Find the speed of m2 when it impacts the floor. 2. In each cycle of its operation, a heat engine expels 2,900 J of energy and performs 1,700 J of mechanical work. Find the thermal efficiency of the engine

Suppose you have a system of two masses strung over a pulley. Mass 1 (6.7 kg) hangs on the right side of the pulley suspended over the ground at height 0.8 m. Mass 2 (2.6 kg) hangs over the left side of the pulley and rests on the ground. The pulley is a uniform disk of mass m and radius 13.9 cm. When the system is released, Mass 1 moves down and Mass 2 moves up, such that Mass 1...

Two masses, mA = 34.0 kg and mB = 40.0 kg , are connected by a
rope that hangs over a pulley (as in the figure (Figure 1)). The
center of the pulley is hollowed out so that you may assume all the
mass of the pulley is in the rim. The radius of the pulley is 0.381
m and the mass of the pulley is 3.10 kg . Initially mA is on the
ground and mB rests 2.50 m...

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

Two blocks of masses m_1 = 4 kg and m_2 = 5kg are connected by a massless string that passes over a massless frictionless pulley as shown in Fig. 6.34. Block m_1 is initially at rest on a smooth horizontal plane while block m_2 is at a height h = 0.75 m above the ground. Use conservation of mechanical energy to find the speed of the masses just before m_2 hits the ground.
Two boxes are connected to a rope, and the rope is hung over a pulley connected to the ceiling
Two boxes are connected to a rope, and the rope is hung over a pulley connected to the ceiling, as shown in the figure below.The masses of the boxes are m1=18.0 kg and m2=12.0 kg, the mass of the pulley is M=5.00 kg, and the radius of the pulley is R=0.300 m. Box m2 is initially on the floor, and box m1 is initially 4.70 m above the floor when it is released from rest. The pulley's axis has negligible...
