A particle A of mass m is situated at highest point of wedge B of mass 2m is released from rest. Then distance travelled by wedge B ( with respect to ground ) when particle A reaches at lowest position. Assume all surfaces are smooth.

A ball of mass m is released from rest from a height H along a smooth, light and fixed tube having a semicircular portion so that the ball just reaches the top of the semicircle. a. Find the radius of the semi-circle. b. Find the maximum force imparted by the ball on the ground.

A small ball is released from rest from point A as shown. if bowl is smooth, than ball will exert more pressure at point B, compared to the situation if bowl is rough. Reason: Linear velocity and hence, centripetal force in smooth situation is more.

A ball of mass 1kg is suspended by an inextensible string 1m long attached to a point O of a smooth horizontal bar resting on fixed smooth supports A and B. The ball is released from rest from the position when the string makes an angle 30^@ with the vertical. The mass of the bar is 4kg . The displacement of bar when ball reaches the other extreme position (in m) is

Figure shows a flat car of mass M on a frictionless road. A small massless wedge is fitted on it as shown. A small ball of mass m is released from the top of the wedge, it slides over it and falls in the hole at distance l from the initial position of the ball. Find the distance the flat car moves till the ball gets into the hole.
