A mass m slides down a smooth inclined plane of inclination `alpha` and draws another mass from rest through a distance d meter in t second along a smooth horizontal table which is on level with the top of the plane over which the string passes. Find m' /m.

A block of mass m is placed on a smooth inclined plane of inclination theta with the horizontal. The force exerted by the plane on the block has a magnitude

A disc of mass m slides with the zero initial velocity down an inclined plane of inclination theta to the harizontal, having traveled the distance d along the horizontal plane, the disc stops. Find the work performed by the friction over the whole distance, assuming the friction coefficient mu for both the inclined and horizontal planes.

The length of a smooth inclined plane of incilination 30^(@) is 5 m. The work done is moving a 10kg mass from the bottom of the inclined plane to top is
