A uniform solid cylinder of mass M and radius R rolls a rough inclined plane with its axis perpendicular to the line of greatest slope as shown in figure-5.75. As the cylinder rolls it winds up a light string which passes over a light and smooth pulley and attached to a mass m , the part of the string between pulley and cylinder being parallel to the line of greatest slope. Prove that the tension in the string is T = [((3 + 4 "sin"theta) M"mg")/(3M + 8m)]

A small ball is projected up a smooth inclined plane with an initial speed of 10 m//s along the direction at 30^(@) to the bottom edge of the slope. It returns to the edge after 2s. The ball is in constant with the inclined plane throughout the process. What is the inclination angle of the plane?

A particle is projected from surface of the inclined plane with speed u and at an angle theta with the horizontal. After some time the particle collides elastically with the smooth fixed inclined plane for the first time and subsequently moves in vertical direction. Starting from projection, find the time taken by the particle to reach maximum height. (Neglect time of collision).

A wedge of mass M and angle alpha rests on a smooth horizontal plane. A smooth sphere of mass m strickes it in a direction perpendicular to its inclined face and rebounds. If the coefficient of restitution is e, find the ratio of the speed of the sphere just before and just after the impact.
