Complete Elasticity

Elastic Limit

In the figure, the block of mass m, attached to the spring of stiffness k is in correct with the completely elastic wall, and the compression in the spring is e. The spring is compressed further by e by displacing the block towards left and is then released. If the collision between the block and the wall is completely eleastic then the time period of oscillation of the block will be

Two massless string of length 5 m hang from the ceiling very near to each other as shown in the figure. Two balls A and B of masses 0.25kg and 0.5kg are attached to the string. The ball A is released from rest at a height 0.45m as shown in the figure. The collision between two balls is completely elastic. Immediately after the collision, the kinetic energy of ball B is 1 J The velocity of ball A just after the collision is

A mass of 3M moving at a speed v collides with a mass of M moving directly towards it, also with a speed v .If the collision is completely elastic, the total kinetic energy after the collision is K_(e) .If the masses stick together,the total kinetic energy after the collision is K_(s) .What is the ratio (K_(e))/(K_(s)) ?

A massive vertical wall is approaching a man at a speed mu . When it is at a distance of 10m, the man throws a ball with speed 10 m/s at an angle of 37^(@) , which after having a completely elastic collision with the wall, reaches back directly into the hands of the man. The velocity of the wall is

In the figure shown surface is frictionless and spring is in natural condition. If x_(1), x_(2) " and " x_(3) are the maximum compression in spring for elastic, completely inelastic and inelastic (e=0.5) respectively then :

Define the terms Elastic collision and Inelastic collision. What is the difference between an inelastic collision and a completely inelastic collision ?
