Question

D-3.a Mass A hits B inelastically (e = 0) while moving horizontally with some velocity along the common line of centres of the three equal masses each of same mass. Initially mass B and C are stationary and the spring is unstretched. Then which is incorrect.

• A. compression will be maximum when blocks have same velocity.
• B. velocity of C is maximum when (A + B) is at rest.
• C. velocity of C is maximum when spring is undeformed.
• D. velocity of C is minimum when spring is undeformed.
