A small block is shot into each of the four tracks as shown below. Each of the tracks rises to the same height. The speed with which the block enters the tracks is the same in all cases. At the highest point of the track, the normal reaction is maximum in :

A small block is shot into each of the four track as shown in Fig 15.7.1. Each of the track rises to the same height. The speed with which the block enters the track is the same in all cases. At the highest point of the track, the normal reaction is maximum in

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

A flexible track is fixed in two alternative arrangements, as shown in the figure. A toy car is released at rest and slides down the track air resistance can be ignored. The length of the track used is the same in each case and the height through which it falls from the bench to the floor is the same. codes:

A flexible smooth track is fixed in two alternate arrangments, as shown in figure -1 and 2. the length of the track used is the same in each case, and the height through which it falls from the bench to the floor is the same. A toy car is released at rest and slides down the track. air resistance can be ignored.

A small block of mass m is pushed on a smooth track from position A with a velocity 2sqrt5 times the minimum velocity required to reach point D. The block will leave the contact with track at the point where normal force between them becomes zero. Find where the maximum contact force occurs between the block and the track.

A small roller coaster starts at point A with a speed u on a curved track as shown in the figure The friction between the roller coaster and the track is negligible and it always remains in contact with the track. The speed of roller coaster at point D on the track will be
