In figure ABCDE is a channel in the vertical plane, part BCDE being circular with radius r. A ball is released from A and slides without friction and without rolling. It will complete the loop path when

In the track shown in figure -3.94 section AB is a quadant of a circle of 1 metre radius in vertical plane. A block is released at A and slides without friction until it reaches at B. After B it moves on a rough horizontal floor and comes to rest at D, 3 metres from B the coefficient of friction between floor and the body will be :

In a fixed quarter circular track of radius R which lies in a vertical plane, a block is released from point A and it leaves the path at point B. The radius of curvature of its trajectory when it just leaves the path will be

A spherical rigid ball is realeased from rest and starts rolling down an inclined plane from height h=7m, as shown in the figure. It hits a block at rest on the horizontal plane (assme elastic collision). If the mass of both the ball and the block is m and the ball is rolling without sliding, then the speed of the block after collision is close to

An inclined track ends in a circular loop of radius 'r'. From what height on the track a particle should be released so that it completes that loop in the vertical plane?

A ball rolls down an inclined plane and acquires a velocity v_(r) when it reaches the bottom of the plane. If the same ball slides without friction and acquires rolling from the same height down an equally inclined smooth plane and acquires a velocity v_(s) (then which of the following statements are not correct?

A frictionless track ABCDE ends in a circular loop of radius R. A body slides down the track from point A which is at height h = 5cm. Maximum value of R for a body to complete the loop successfully is

A disc of mass m is connected with an ideal spring of stiffness k . If it is released from rest, it rolls without sliding on an inclination plane. The maximum elongation of the spring is:
