a uniform solid cylinder of mass m and radius r is released from the top of a rough inclined plane of inclination theta and length of slant = l . the coefficient of friction is muu=(1/4)tan theta .find time taken by cyillender to reach the bottom , total kinetic energy of the cylinder at the bottom , total work done by friction.
pls reply fast...
As the cylinder is sliding down the inclined plane, force of friction F acts up the plane. If a is acceleration produced in the block, then net force on the cylinder down the plane is,
