A solid disk of unknown mass ad known radius R is used as a pulley in a lab experiment, as shown. A small block of mass m is attached to a string, the other end of which is attached to the pulley and wrapped around it several times. The block of mass m is released from rest and takes a time t...

Marks: 1 A 10-kg block on a horizontal frictionless surface is attached to a light spring (force constant = 0.80 kN/m). The block is initially at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to the surface is applied to the block, as shown. What is the speed...

A 230 g block is attached to a horizontal spring and executes simple harmonic motion with a period of 0.200 s. If the total energy of the system is 3.00 J.

A 1240-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam. Using the data shown in the figure, find (a) the magnitude of the tension in the wire and the magnitudes of the (b) horizontal and (c)...

I attached my assignment

A m = 5 kg block rests on a frictionless floor. It is attached to a L = 4 m long spring hanging straight down. The spring has spring constant k = 17 N/m and is just relaxed in its vertical position. The block is pulled d = 3 m to one side.
