Problem #4 On a billiards table, the 7-ball and the 8-ball are initially at rest and touching each other. All three balls have the same mass m. You hit the cue ball in such a way that it acquires a horizontal speed of 1.7 m/s before hitting the 7-ball and 8-ball simultaneously. After the collision, the cue ball is at rest, and the other two balls are each moving at 45° from the direction that the cue ball was moving. Assuming that the tablecloth's friction is much smaller than that of the collision force, find the final speed of the 7-ball and 8-ball immediately after the collision. Before: After: 7 y Vcue 45° 8. 8.

Sphere m1 with a mass of 1.0 kg collides with m2, which also has a mass of 1.0 kg, in an elastic collision. If v2f= 15 m/s and θ2= 40°, determine v1i. (Hint: An elastic collision requires that the after-collision angle between the two velocities must be 90°.)
A shell is shot with an initial velocity 0 of 27 m/s, at an angle of 0o = 56° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass (see the figure). One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that air drag is negligible? Explosion 7
A 78.9 kg linebacker (X) is running at 6.83 m/s directly toward the sideline of a football field. He tackles a 89.1 kg running back (O) moving at 9.27 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go out‑of‑bounds at an angle ϕ relative to the sideline, as shown in the diagrams. What is the common speed ?fvf of the players immediately after their impact? What is the angle ϕ of their motion relative to the sideline?
Ball A has a mass of 2 kg, B has a mass of 4 kg. The initial speed of A is as shown, that is, 2 m/s to the right. Ball B is initially at rest. Assuming no friction and the coefficient of restitution e = 0.8, determine the final speed and direction of balls A and B. Dice: The angle between the center lines and the center of balls A and B is 30°
A 80.1 kg linebacker (X) is running at 6.71 m/s directly toward the sideline of a football field. He tackles a 91.7 kg running back (O) moving at 9.49 m/s straight toward the goal line, perpendicular to the original direction of the linebacker. As a result of the collision, both players momentarily leave the ground and go out‑of‑bounds at an angle ϕ relative to the sideline, as shown in the diagrams. What is the common speed ?f of the players immediately after their impact? What is the angle ϕ of their motion relative to the sideline?
Treat the collision as elastic. A moving billiard ball hits an identical (except for color) stationary ball. After the collision, the orange ball always goes off in the positive x-direction. The final speeds are v and V. Calculate the angle θ that the green ball goes off in. (θ should be positive.) V0 = the initial green body's speed = 6 m/s M = the mass of both balls = 6 kg φ = the incoming green ball's angle = 70o It's always a good idea to check your answer with the momentum-conservation and energy-conservation equations.
A block is released from rest at the top of the frictionless ramp shown in the figure. Mass 1 is 1.53 kg and it is released from a height of 1.01 m above the table. The block collides elastically with block 2, initially at rest. Mass 2 is 4.14 kg. How far from the base of the table does mass 1 eventually land if the table has a height of 2.54 m? (Take the initial direction of block one as positive.)

In a game of billiards, the cue ball is traveling eastward when it strikes a second ball that is initially at rest. After the collision, the cue ball moves at 4.65 m/s, 25.0° south of east, and the second ball's speed is 3.11 m/s. At what angle (north of east) does the second ball travel? Assume each ball has a mass of 162 g. Submit A Tries 0/5 What was the speed of the cue ball prior to the collision? Tries 0/5 Is the kinetic energy of the colliding balls conserved?
