Question

The figure shows a graph between velocity and displacement (from mean position) of a particle performing SHM:

  1. the time period of the particle is 1.57s    
  2. the maximum acceleration will be 40cm/s2    
  3. the velocity of particle is 2 square root of 21 cm/s when it is at a distance 1 cm from the mean position.    
  4. none of these    

The correct answer is: none of these

In the figure shown, two identical discs of radius R each are placed on a smooth horizontal plane. Thread unwraps without slack from discs when they move away from each other. At any instant acceleration of centres of disc A and B are a2 and a1 respectively in opposite direction while their angular acceleration aare aand respectively. If string unwraps from discs without slipping then

A uniform disc of mass M and radius R is supported vertically by a pivot at its periphery as shown. A particle of mass M is fixed to the rim and raised to the highest point above the centre. The system is then released from rest and it can rotate about its pivot freely. The angular speed of the system when the attached object is directly beneath the pivot is

One ice skater of mass m moves with speed 2v to the right, while another of the same mass m moves with speed v toward the left, as shown in figure I. Their paths are separated by a distance b. At t = 0, when they are both at x = 0, they grasp a pole of length b and negligible mass. For t > 0, consider the system as a rigid body of two masses m separated by distance b, as shown in figure II. Which of the following is the correct formula for the motion after t = 0 of the skater initially at y=b/2?
