The final speed of the disks.

Question

Two friends are playing pool at arcade center. One guy hit the cue ball to strike at another ball where it is initially at rest. After the collision caused by the ball that was at rest, the cue ball moves at 2.50 m/s along a line making an angle 0-14.0° with its original direction of motion and the second ball has a speed of 1.50 m/s. Find the answer for Part a,b and c. Part A: Find the angle e between the direction of the motion of the second ball and the original direction of motion of the cue ball. Part B: Find the cue ball's original speed? Part C: Figure out whether kinetic energy is conserved?

Two particles undergo an inelastic collision whose final kinetic energy represents 31% of the initial kinetic energy. Before the collision, particle 1 of mass mi = 0.5 kg moves at 5 m/s towards the east and particle 2 of mass m2 = 1 kg moves at 4 m/s at 30 ° south of west. After the collision, the velocity vector of particle 1 is oriented to the north. We will use the following notation: u1 the velocity vector of particle 1 before the collision, u2 the speed vector of particle 2 before the collision, v 1 the speed vector of the particle 1 after the collision and v 2 the velocity vector of particle 2 after the collision. a) Determine the components of the velocity vector of particle 2 before the collision. b) Determine the modulus of the velocity vector of particle 1 after the collision. c) Determine the modulus and orientation of the velocity vector of particle 2 after the collision.
