a uniform sphere rolls on a horizontal surface at 20m/s and then rolls up an incline that is inclined at 30 degrees to a height h from the ground. if frictional forces are negligible , show that the height h is independent of the mass of the sphere hence calculate the value of h.

A billiard ball of radius "a" and mass "m" is initially spinning counterclockwise about a horizontal axis with angular speed ω0=-v0/a and with a forward speed v0. The coefficient of kinetic friction between the ball and the billiard table is μ. Given Determine: a. The distance the ball...

A rotating wheel accelerates uniformly at 6.2 rad/s, and completes 25 revolutions during a 5.0 s interval. (a) What is the angular velocity of the wheel At the start of the 5.0 s interval? (b) What is the angular velocity of the wheel at The end of the 5.0 s interval?

A body starts from rest and falls through a height of 19.6m.what time does it take to fall through the last 4.9m. Of its fall?

Q-if 'm' is the mass of a body, projected with velocity 'u' making an angle'x' with the horizontal, the change in velocity between the point of projection and impact will be? Q-a solid sphere and solid cylinder having the same mass and radius roll down the same inclined plane . The ratio of their...
