A wooden block with m1 31kg is sliding across a, Ask an Expert

Academics

A wooden block with m1 = 3.1kg is sliding across a frictionless surface in the ?x direction at 5.2 m/s. A smaller wooden block with m2 = 1 kg block is traveling in the +x direction at 3.1 m/s.

1) Find the velocity vcm of the center of mass.

2) What is the velocity of m1 in the COM frame?

3) What is the velocity of m2 in the COM frame?

4) Now they make a head-on elastic collision. (This means that in the COM frame, the velocity of each is reversed.) What is the velocity of m1 in the COM frame after the collision?

5) What is the velocity of m2 in the COM frame after the collision?

6) Transform back into the original frame by adding vcm to the velocity of each block. What is the velocity of the m1 block in the lab frame after the collision?

7) What is the velocity of the m2 block in the lab frame after the collision?
