() THE FOLLOWING QUESTIONS ARE BASED ON THE INFORMATION GIVEN BELOW. Block of mass 9 kg moving with velocity v = 39 m/s on a frictionless plane collides block m, which is connected to block ma by a long, massless spring with spring constant k = 8000 N/m; see the figure. Each of blocks m2 and mz has a mass of 3 kg. Before the collision, blocks m2 and mz are stationary and the spring is relaxed. k ww m2 m3 Frictionless- • For parts A, B and C assume that the collision of blocks m, and m, is completely inelastic. (Because the spring is relaxed before the collision, block m, does not move at the instant of impact, therefore (m, +m2) must move through a finite displacement before any force acts on m3 and cause it to move.) • For parts D and E assume that the collision of blocks m, and m, is elastic. (Because the spring is relaxed before the collision, block m3 does not move at the instant of impact, therefore m2 must move through a finite displacement before any force acts on m3 and cause it to move.) A) After the collision, what is the maximum kinetic energy of block m3 in units of joules? Answer:

A projectile of mass 2.0 kg is fired in the air at an angle of 40.0 to the horizon at a speed of 50.0 m/s. At the highest point in its flight, the projectile breaks into three parts of mass 1.0 kg, 0.7 kg, and 0.3 kg. The 1.0-kg part falls straight down after breakup with an initial speed of 10.0 m/s, the 0.7-kg part moves in the original forward direction, and the 0.3-kg part goes straight up. Launch a. Find the speeds of the 0.3-kg and 0.7-kg pieces immediately after the break-up. b. How high from the break-up point does the 0.3-kg piece go before coming to rest? c. Where does the 0.7-kg piece land relative to where it was fired from?

A billiard ball, labeled 1, moving horizontally strikes another billiard ball, labeled 2, at rest. Before impact, ball 1 was moving at a speed of 3.00 m/s, and after impact it is moving at 0.50 m/s at 50 from the original direction.
