A cube of mass M starts of rest from point 1 at a height 4R, where R is the radius of the circular track. The cube slides down the frictionless track and around the loop. The force which the track exerts on the cube at point 2 is :

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. The loop track consisting of a ramp and a circular loop of radius R shown in the figure. Assume that the track is frictionless. When the object is at the top of the circular track it pushes against the track with a force equal to three times its weight. What height was the object dropped from?

A particle of mass m is released from point A as shown in the gigure. Would it loop the loop if H=4r? What is the force on the circular track when it is at point (a) B, (b) C?

Figure shows a loop track whose lower part ends into a circular track of radius R and centre O. A small solid sphere of mass M rolls without slipping along the loop track from the end A at a height 6R from the bottom of the track. What is the horizontal force acting on the sphere, when it rises up to the point P in level with the centre O of the circular part ?

A block of mass M = 2 kg with a semicircular track of radius R = 1.1 m rests on a horizontal frictionless surface. A uniform cylinder of radius r = 10 cm and mass = 1.0 kg is released from rest from the top point A. the cylinder slips on the semicircular frictionless track. The speed of the block when the cylinder reaches the bottom of the track at B is (g =10ms^(-2))
