A massless, frictionless pulley has a rope with two weights suspended from it. The masses of the blocks are as follows: MA = 2m and MB = m. What is the tension in the rope when the blocks are released from rest?

What are two different ways you could find the value of a? explain these methods.

A2.00-m long piano wire with a mass per unit length of 12.0 g/m is under a tension of 8.00 kn. what is the frequency of the fundamental mode of vibration of this wire?

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
