A cylinder of mass 10 kg and radius 15 cm is rolling perfectly on a plane of inclination 30^@ . The co-efficient of static friction mus = 0.25 :- How much is the force of friction acting on the cylinder ?

Derive the expression for acceleration and tension in a string in a connected motion.

A stone of mass 0.25 kg tied to the end of a string is whirled round in a circle of radius 1.5 m with a speed of 40 rev.//min in a horizontal plane. What is the tension in the string ? What is the maximum speed with which the stone can be whirled around if the string can withstand a maximum tension of 200 N ?

A block of mass 15 kg is placed on a long trolley. The coeffcient os static friction between the block and the trolley is 0.18. The trolley accelerates from rest with 0.5 m s^-2 for 20 s and then moves with uniform velocity. Discuss the motion of the block as viewed by:- an observer moving with the trolley.
