- Part D and Part EPart A A block of mass 2.55 kg slides down a 30.0° incline which is 3.60 m high. At the bottom, it strikes a block of mass 7.60 kg which is at rest on a horizontal surface. (Assume a smooth transition at the bottom of the incline.)

Immediately before the collision, player 1 is slipping with a velocity of v₁ due north and player 2 is sliding with a velocity of v2 = 2v1 due east. 3a. Sketch the situation, placing careful labels, and write formulae for the initial momenta of the two players. Might want to chose a coordinate system that will help you figure out how to add together these momenta. 3b. What is the magnitude of the total momentum of the system of these two players before they collide? 3c. What are the magnitude and direction of the velocity at which the two players move together immediately after the collision? 3d. Calculate the loss of kinetic energy associated with this collision.
- 2.5 Concrete mixer* In a concrete mixer, cement, gravel, and water are mixed by tum- bling action in a slowly rotating drum. If the drum spins too fast the ingredients stick to the drum wall instead of mixing. Assume that the drum of a mixer has radius R = 0.5 m and that it is mounted with its axle horizontal. What is the fastest the drum can rotate without the ingredients sticking to the wall all the time? Assume g = 9.8 m/s?.Just answer #2 parts A and B please.E To Two blocks, labeled D and E, are connected by an essentially massless string that runs over an essentially massless and frictionless pulley, as shown in Figure 2, above. Block E hangs straight down and is initially moving downward with a speed of 3.82 meters per second. Block D is on an inclined plane, inclined at an angle of theta = 0 = 28.6 degrees above horizontal. There is no friction between block D and most of the plane, but there is friction (with a coefficient of kinetic friction equal to 0.49) between block D and a region of length L = 0.628 meters. Block D will slide over that region (and pass it completely) before it gets to the end of the plane. Block D has a mass of 0.74 kg, while block E has a mass of 0.98 kg. The only significant forces acting on the blocks are friction acting on block D (while in contact with the region with friction), normal forces, tension forces, and gravity (with g = 9.81 m/s2). Calculate the speed of block D (in units of meters per second)…
