Puck A (with mass 0.250 kg) is travelling toward puck B (with mass 0.350 kg), which is originally at rest, on a frictionless, horizontal air table. Puck A has a velocity to the left of 0.120 m/s after the contact, while puck B has a velocity to the right of 0.650 m/s.
(a) How fast was puck A traveling before to the collision?
(b) Determine the change in the system's overall kinetic energy that results from the impact.
Determine all of the first order partial derivatives for the following functions:
