A solid cylinder at rest at top of an inclined plane of height 2.7 m, rolls down without slipping. If the same cylinder has to slide down a frictionless inclined plane and acquire the same velocity as that acquired by centre of mass of rolling cylinder, at the bottom of inclined plane, the height of the inclined plane should be

A solid sphere and a ring of same radius roll down an inclined plane without slipping . Both start from rest from the top of the inclined plane. If the sphere and the ring reach the bottom of the inclined plane with velocities v_s and v_r repectively. , then (v_r^2)/(v_s^2) is

A body of mass 'm' slides down a smooth inclined plane having an inclination of 45° with the horizontal. It takes 2s to reach the bottom. If the body is placed on a similar plane having coefficient friction 0.5, what is the time taken for it to reach the bottom?

A rough inclined plane BCE of height (25/6)m is kept on a rectangular wooden black ABCD of height 10 m , as shown in the figure. A small block is allowed to slide down from the top E of the inclined plane. The coefficient of kinetic friction between the block and the inclined plane is 1/8 and the angle of inclination of the inclined plane is sin^-1 (0.6) . IF the small block finally reaches the ground at a point F, then DF will (Acceleration due to gravity, g=10 ms^-2 )

The upper half of an inclined plane with an angle of inclination 4, is smooth while the lower half is rough. A body starting from rest at the top of the inclined plane comes to rest at the bottom of the inclined plane. Then the coefficient of friction for the lower half is
