coefficient of kinetic friction 2 m, h A bullet of mass m¡ traveling horizontally with speed u hits a block of mass m2 that is originally at rest and becomes embedded in the block. After the collision, the block slides horizontally a distance d on a surface with friction, and then falls off the surface at a height h as shown. The coefficient of kinetic friction between the block and the surface is µk. Assume the collision is nearly instantaneous and all distances are large compared to the size of the block. Neglect air resistance.

云 HI 5 F. %24 -10 Part A Jeanette is playing in a 9-ball pool tournament. She will win if she sinks the 9-ball from the final rack, so she needs to line up her shot precisely. Both the cue ball and the 9-ball have mass m, and the cue ball is hit at an initial speed of v. Jeanette carefully hits the cue ball into the 9-ball off center, so that when the balls collide, they move away from each other at the same angle 0 from the direction in which the cue ball was originally traveling (see figure). Furthermore, after the collision, the cue ball moves away at speed vf, while the 9-ball moves at speed vp. (Figure 1) Find the angle 0 that the 9-ball travels away from the horizontal, as shown in the figure. Express your answer in degrees to three significant figures. > View Available Hint(s) For the purposes of this problem, assume that the collision is perfectly elastic, neglect friction, and ignore the spinning of the balls.

In addition to m1, what is the minimum necessary information that would allow you to determine the mass of the second object? A. The final speed of object 1B. The initial speed of object 1C. The final speed of object 2D. Any 2 of the above values
Two spheres, each of mass m, can slide freely on a frictionless, horizontal surface. Sphere A is moving at a speed v0 = 16 ft/s when it strikes sphere B which is at rest, and the impact causes sphere B to break into two pieces, each of mass m/2.a) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the velocity of sphere A after the collision.b) Knowing that 0.7 s after the collision one piece reaches Point C and 1.17 s after the collision the other piece reaches Point D, determine the angle θ and the speeds of the two pieces after the collision.
Treat the collision as elastic. A moving billiard ball hits an identical (except for color) stationary ball.
1D Elastic Collision 1. You have two balls. They will collide elastically in 1D. Choose the following: • The masses of the balls (they cannot have the same mass). • The initial velocities of the balls (neither can be at rest). Solve for the final velocities of the balls after the collision using Conservation of Momentum and Conservation of Energy • Solve, you must draw a picture, set photo 1 and photo 2, and draw origin and axes?
