Center of MassHard
Question
A block of mass m moving with a velocity v0 collides with a stationary block of mass M at the back of which a spring of spring constant K is attached, as shown in the figure. Select the CORRECT alternative (s) :
Options
A.The velocity of center of mass is 
v0
v0B.The initial kinetic energy of the system in the center of mass frame is 
C.The maximum compression in the spring is v0 
D.When the spring is in the state of maximum compression the kinetic energy in the center of mass frame is zero
Solution
(A) VCM = 
(D) At maximum compression both block moves together so speed of centre of mass is also same.
(D) At maximum compression both block moves together so speed of centre of mass is also same.
