Two blocks of mass 3 kg and 6 kg

Asked by admin @ 20/08/2021 in Math viewed by 293 People

Two blocks of mass 3 kg and 6 kg respectively are placed on a smooth horizontal surface. they are connected by a light spring of force constant k = 200 n/m. initially the spring is unstretched. the indicated velocities are imparted to the blocks. the maximum extension of the spring will be

Answered by admin @ 20/08/2021

Thus by using conservation of momentum the common velocity at maximum extension is found out and thereafter by energy conservation the maximum extension is found out
