If the body starts from rest from the top of the rough inclined plane of length 1, time taken to reach the bottom of the plane is

An object of mass m is released from rest from the top of a smooth inclined plane of height h. Its speed at the bottom of the plane is proportional to

A block released from rest from the top of a smooth inclined plane of inclination 45^(@) takes time 't' to reach the bottom . The same block released from rest , from top of a rough inclined plane of same inclination , takes time '2t' to reach the bottom , coefficient of friction is :

A block released from rest from the top of a smooth inclined plane of angle theta_1 reaches the bottom in time t_1 . The same block released from rest from the top of another smooth inclined plane of angle theta_2 reaches the bottom in time t_2 If the two inclined planes have the same height, the relation between t_1 and t_2 is

A block is released from the top of the smooth inclined plane of height h . Find the speed of the block as it reaches the bottom of the plane.

A body is released from rest from the top of an inclined plane of length L and angle of inclination theta ,.The top of plane of length (L)/(N) (N>1) is smooth and the remaining part is rough.If the body comes to rest on reaching the bottom of the plane, then the value of coefficient of friction of rough surface is ?

A block of mass m is released from the top of a mooth inclined plane of height h its speed at the bottom of the plane is proportion to
