A sphere of mass m and rdius r is released from rest at point A on a track in vertical plane. The track is rough enough to support rolling between A and B and from B onwards it is smooth. The maximum height attained by sphere from ground on its journey from B onwards is

A solid sphere is released from rest from height 'h' as shown. Left side track is sufficient rough for pure rolling but another side is smooth as shown in the figure. Find maximum height attain by the sphere on the smooth part of the track.

An uniform hollow hemisphere of mass m and radius r is released from rest on a smooth horizontal surface with its open face vertical initially. Maximum normal reaction between hemisphere and ground during motion is -

A ball is released from point A as shown in figure. The ball leaves the track at B. All surfaces are smooth. If track makes an angle 30^(@) with horizontal at B, then maximum height attained by ball will be

A sphere of mass m and radius r rolls on a horizontal plane without slipping with a speed u . Now it rolls up vertically, then maximum height it would be attain will be

Two solid spheres P and Q are released from rest from the same point on an inclined plane. Plane is sufficiently rough to provide pure rolling Mass of P is greater than the mass of Q whereas radius of Q is greater than the radius of P

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 solid spherical ball of mass m is released from the topmost point of the shown semi - spherical shell. The track is sufficiently rough to enablle to enable pure rolling motion. The normal force between the ball and the shell at the lowest position is

A body of mass 10kg is at height of 10m at point A as shown on a smooth track. Find speed at B.

A smooth track, fixed to the ground, is in the shape of a quarter of a circle. Two small blocks of mass 3m and 2m are released from the two edges A and B of the circular track. The masses slide down and collide at centre O of the track. Vertical height of A and B from O is h = 2m . Collision is elastic. Find the maximum height (above O) attained by the block of mass 2m after collision
