A solid cylinder of mass 2.00kg and radius 1.50x10^-2m is free to rotate on a frictionless axle. A mass of 2.00kg hangs from a string wrapped around the cylinder. When the hanging mass is released it falls and unwinds the string from the cylinder. Solve for the tension in the string and the acceleration of the falling mass.
The coefficient of friction between the ladder and ground is 0.6 and the ladder makes an angle, theta with the ground equal to 50 degrees. Explain how far up the ladder can an 800N man climb before the ladder begins to slip?
A child goes down a playground slide with an acceleration of 1.30. Find out the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 34.0 below the horizontal.
