Problem a 125 kg block lies on a 300 degree incline a rope, Ask an Expert

Academics

Problem: A 12.5 Kg block lies on a 30.0 degree incline. A rope connects the block to the upper end of the incline. The rope is parallel to the incline.

Part A: If the rope has a linear density of 0.0128 kg/m, what is the wave speed of waves on the rope?

I need help to solve the above problem and ignore the mass of the rope when calculating the tension in the rope.
