An object of mass `m` is allowed to fall from rest along a rough inclined plane. The speed of the object on reaching the bottom of the plane is proportional to:

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

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

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

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

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.

Three different objects of masses m_(1) , m_(2) and m_(2) are allowed to fall from rest and from the same point O along three different frictionless paths. The speeds of three objects on reaching the ground will be:

Three different objects of masses m_(1) , m_(2) and m_(2) are allowed to fall from rest and from the same point O along three different frictionless paths. The speeds of three objects on reaching the ground will be:

A solid sphere of mass m rolls down an inclined plane without slipping from rest at the top of an inclined plane.The linear speed of the sphere at the bottom of the inclined plane is v .The kinetic energy of the sphere at the bottom is

Three different objects of masses m_(1), m_(2) and m_(3) are allowed to fall from rest and from the same point O along three different frictionless paths. The speeds of three objects, on reaching the ground, will be in the ratio of
