During a football game, a receiver has just caught a pass and is standing still. Before he can move, a tackler, running at a velocity of +4.1 m/s, grabs and holds onto him so that they move off together with a velocity of +2.4 m/s. If the mass of the tackler is 125 kg, determine the mass of the receiver. Assume momentum is conserved.
A golf ball traveling 3 m/s to the right has a head-on with astationary bowling ball in a friction-free environment. If the collision is almost perfectly elastic, the speed of the golf ball immediately after the collision is:
For ideal gas CO2, it is compressed from an initial state of 120Kpa, 340k to a final state of 900kpa, 1200k. Determine the specific entropy change
A 1.25 kg block slides 3 m down a smooth incline. At the bottom of the incline it has an elastic collision with a 3.50 kg block which is initially at rest. What is the maximum distance the1.25 kg block will slide up the incline after the collision?
