two blocks of masses m and 3m are placed on a frictionless horizontal surface

 

Ques:

Two blocks of masses m and 3m are placed on a frictionless, horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together with the spring between them. A cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right with a speed of 2.00 m/s.

(a) What is the velocity of the block of mass m?

(b) Find the system’s original elastic potential energy, taking m = 0.350 kg.

A 1.0 kg block and a 2.0 kg block are pressed together on a horizontal frictionless surface with a compressed spring between them. They are not attached to the spring. After they are released and have both moved free of the spring.

A. the magnitude of the momentum of the heavier block will be greater than the magnitude of the momentum of the lighter block.
B. the lighter block will have more kinetic energy than the heavier block.
C. both blocks will both have the same amount of kinetic energy.
D. both blocks will have equal speeds.
E. the heavier block will have more kinetic energy than the lighter block

Two blocks of masses M and 3M are placed on a horizontal, frictionless surface. A light spring is attached to one of them, and the blocks are pushed together with the spring between them. When the blocks released, the block of mass 3m moves to the right with a speed of 2.00m/s

(a) What is the velocity of the block of mass M?
