Friction on ramp;

Consider a frictionless ramp on which a smooth object is made to side down from an initial height 'h'. The distance 'd' necessary to stop the object on a flat track ( or coefficient of friction 'mu'), kept at the ramp end is

This diagram depicts a block sliding along a, frictionless ramp in vertical plane. The eightl numbered arrows in the diagram represent directions, to be referred to when answering the questions. The direction of the acceleration of the block (after leaving the ramp) at position III is best represented by which of the arrows in the diagram ?

In Fig. 5-45, a crate of mass m = 115 kg is pushed at constant speed up a frictionless ramp (theta=30.0^(@)) by a horizontal force vec(F) . What are the magnitudes of (a) vec(F) and (b) the force on the crate from the ramp ?

A marble and a cube are placed at the top of a ramp. Starting from rest at the same height, the marble rolls and the cube slides (no kinetic friction) down the ramp. Determine the ratio of the center-of-mass speed of the cube to the center-of-mass speed of the marble at the bottom of the ramp.

In the picture shown, a ball standing from rest rolls down a ramp AB,goes along at the horizontal bottom BC, and then backs up a smaller ramp CD, thereafter rolls on horizontal plance DE Ignore friction and air resistance. Which of the following figure shows variation in speed with time?
