Two blocks of masses m 1 = 2.00 kg and m 2 = 4.00 kg are each
released from rest at a height of h = 5.00 m on a frictionless
track, as shown in Figure P6.70, and undergo an elastic headon
collision. (a) Determine the velocity of each block just
before the collision. (b) Determine the velocity of each block
immediately after the collision. (c) Determine the maximum
heights to which m 1 and m 2 rise after the collision.

Step 1

a)

Velocity of the block just before the collision

Velocity of m1 block just before the collision

Initial PE of m1 = final KE

Step 2

Velocity of m2 block just before the collision

Initial PE of m1 = final KE

Step 3

b)

The formula to calculate the cons...
