A mass on a horizontal table is attached by a thin string that passes over a frictionless, massless pulley to a 2.5 kg mass that hangs over the side of the table 1 m above the ground. The system is released from rest and the 2.5 kg mass strikes the ground at 0.83 s later. The system is now placed in its initial position and a 1.1 kg mass is placed on top of the block of mass m1. Released from rest, the 2.5 kg mass now strikes the ground 1.4 s later. The acceleration of gravity is 9.81 m/s 2.

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...

A mass m1 is connected by a light string that passes over a pulley of mass M to a mass m2 sliding on a frictionless horizontal surface as shown in the figure. There is no slippage between the string and the pulley. The pulley has a radius of 25.0 cm and a moment of inertia of ½ MR2. If m1 is 1.00 kg, m2 is 2.00 kg, and M is 4.00 kg, then what is the acceleration of m1?

A block of mass m1= 4.00 kg moves on the surface of a horizontal
table. The coefficient of kinetic friction k between the table top
and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1
via a string that passes over a frictionless, massless pulley. The
two blocks start from rest and m2 drops by a distance L =1.75 m to
the floor.
