An Atwood machine consists of two masses connected by a light string of fixed length which is wrapped around a frictionless bar. One end of the string is connected to a 6 kg mass (mi), while the other end is connected to a 2 kg mass (m2). The 6 kg mass is 2.5 meters above the flat, horizontal floor, while the 2 kg mass starts at rest on the floor. 3. bar mi 2 m2 A) Calculate the speed of...

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...

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

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 blocks of masses m1 and m2 are connected by a light cord that passes over a pulley of mass M, as shown. Block m2 slides on a frictionless horizontal surface. The blocks and pulley are initially at rest. When m1 is released, the blocks accelerate and the pulley rotates. The total angular momentum of the system of the two blocks and the pulley relative to the axis of rotation of the pulley isthe same at all times.proportional to I1,...
