(a) What was the velocity of the stuck-together objects immediately after the collision?
Vf = m/s
(b) How fast was the PlahDoh moving when it ran into the Styrofoam ball?
vplaydoh = m/s
(c) Determine the average impact force if the collision lasted for 3.6 ms.
Favg = N
(d) How much heat was generated during the collision?
K = J
