1.	A particle of mass 100 g moving at an initial speed u collides with another particle of same mass kept initially at rest. If the total kinetic energy becomes 0.2 J after the collision what could be minimum and the maximum value of u.
Answer» Correct Answer - A::B In elastic collision, velocities are interchanged. So, `v` is minimum `:. 1/2xx0.1xxv^2=0.2` `:. V=2m//s=`minimum value In perfectly inelastic collision, speed of combined mass will remain half. `:. 1/2xx0.1xx(v/2)^2=0.2` `:. v=2sqrt2m//s`=maximum value

The system is released from rest and it becomes taut when `B` falls a distance `0.5 m`. a. Find the common velocity of the two blocks just after the string becomes taut. b. Find the magnitude of impulse on the pulley by the clamp during the small interval while string becomes taut.
A body of mass `1 kg` moving with velocity `1 m//s` makes an elastic one dimesional collision with an identical stationary body. They are in contact for brief time `1 sec`.
