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

The speed at the bottom as well as time taken in both the traks are the same.

B

The speed at the bottom as well as time taken in both the tracks are different

C

The speed at the bottom is different but the time taken in both the tracks are the same.

D

The speed at the bottom is same but the time taken in both the tracks are different.

A particle slides along a track with elevated ends and a flat central part as shown in figure. The flat part has a length l=3m . The curved portions of the track are frictionless. For the flat part, the coefficient of kinetic friction is mu_k=0.2 . The particle is released at point A which is at height h=1.5m above the flat part of the track. Where does the particle finally come to rest?

A small block of mass m slides along a smooth track, as shown in fig. (i) If it starts from rest at P, what is the resulting force acting on it at Q ? (ii) at what height above the bottom of the loop should the block be released so that the force it exerts against the track at the top of the loop equals its weight?

An object of mass m is released from rest at a height h above the surface of a table. The object slides along the inside of the loop.
