A 1772 g mass is on a horizontal surface with μk = 0.330, and is in contact with a massless spring with a force constant of 790 N/m which is compressed. When the spring is released, it does 6.68 J of work on the mass while returning to its equilibrium position. Calculate the distance the spring was...

The rope is inclined at 5 degrees above the horizontal and the tension in the rope is 65N. A) Find the work done by the tension.

A log is floating on swiftly moving water. A stone is dropped from rest from 73.4-m high bridge and lands on the log as it passes under the bridge. If the log moves with a constant speed of 5.57 m/s, what is the horizontal distance between the log and the bridge when the stone is released?
