A block of wood of mass m1 = 0.15 kg slides to the right on a frictionless horizontal table with an unknown speed. It collides with a second piece of wood of mass m2 = 0.30 kg which is stationary and attached to a spring with a spring constant of k = 159.00 N/m. The two pieces of wood stick together, and the spring compresses by an amount of 0.45 m.
(a) What is change in total momentum of the two masses as a result of the collision,
(before the spring compresses)?
ANSWER: __________________ _____
(b) What is the velocity of each mass just after collision (and before the spring
compresses)?
ANSWER: v1f = _______________________ _____
ANSWER: v2f = _______________________ _____
(c) What is the kinetic energy of each mass before collision?
ANSWER: K1i = _______________________ _____
ANSWER: K2i = _______________________ _____
(d) What is the change in total kinetic energy of the two masses as a result of the
collision (before the spring compresses)?
ANSWER: __________________ _____
Answers are suppose to be: A1) 0 A2) 8.46 m/s, 8.46 m/s A3) 48.4 J, 0J A4) -32.3 J
