Bullet B weighs 0.5 oz and blocks A and Cboth weigh 3 lb. The coefficient of friction between the blocks and the plane is Hk = 0.31. Initially the bullet is moving at vo and blocks A and Care at rest (Figure 1). After the bullet passes through A, it becomes embedded in block Cand all three objects come to stop in the positions shown (Figure 2). Determine the initial speed of the bullet vo.

Q16. As shown in the image below, the 0.9-kg ball strikes the rough ground and rebounds. The directions of its velocities before and after the strike are shown. If the speeds are v = 23 m/s and v2 = 11 m/s, determine the magnitude of the ball's linear momentum (in kg-m/s) before it strikes the ground. Please pay attention: the numbers may change since they are randomized. Your answer must include 1 place after the decimal point. V2 V1 45° 30° Your Answer: Answer

Body U with mass 5m is stacked on the top body W with mass m, and released. The bodies are in contact along the frictionless interface at 45° to the vertical. The body U is in contact with the frictionless vertical wall. Body W lies on the floor with coefficient of friction u. Relevant dimensions are shown in the figure. Express the results in terms of given quantities: m, g, h and µ (except when µ is given numerically). You need not evaluate sin 45° = cos 45° = 2/2. h U: 5m C 45 D W: m 3h
