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.
Two shuffleboard disks of equal mass, one orange and the other yellow, are involved in an elastic, glancing collision. The yellow disk is initially at rest and is struck by the orange disk moving with a speed υi. After the collision, the orange disk moves along a direction that makes an angle θ with its initial direction of motion. The velocities of the two disks are perpendicular after the collision. Determine the final speed of each disk.
