Questions
One end of a spring of force constant k is fixed to a vertical wall and the other to a block of mass m resting on a smooth horizontal surface. There is another wall at a distance from the black. The spring is then compressed by and released. The time taken to strike the wall is
detailed solution
Correct option is C
The total time from A to CtAc=tAB+tBC=(T/4)+tBCwhere T = time period of oscillation of spring mass system tBC can be obtained from, BC=ABsin(2π/T) tBCPutting BCAB=12 we obtain tBC=T12⇒tAC=T4+T12=2π3mk.Similar Questions
An ideal spring with spring-constant K is hung from the ceiling and a block of mass M is attached to its lower end. The mass is released with the spring initially unstretched. Then the maximum extension in the spring is
