Center of MassHard
Question
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 is :
Options
A.30 cm
B.25 cm
C.20 cm
D.15 cm
Solution
In the centre of mass frame
200 x2 =
x =
= 0.3 m
= 30 cm
200 x2 =
x =
= 0.3 m= 30 cm
