Two block-spring mass system are moving ...

Two block-spring mass system are moving on smooth horizontal surface as shown in the figure as t=0. find out the minimum time t when the spring is maximum elongated `l_(0)` is the natural length of spring.

Text Solution

Verified by Experts

`T=2pisqrt((4)/(9pi^(2)))=(2xx2)/(3)=(4)/(3)`
`t=(3T)/(4)=(3)/(4)xx((4)/(3))=1`

A dumbbell consists of two balls A and B of mass m=1 kg and connected by a spring. The whole system is placed on a smooth horizontal surface as shown in the figure. Initially the spring is at its natural length, the ball B is imparted a velocity v_(0)=8/(sqrt(7))m//s in the direction shown. The spring constant of the spring is adjusted so that the length of the spring at maximum elongation is twice that of the natural, length of the spring. Find the maximum potential energy stored (in Joule) in the spring during the motion.
