To solve for the final velocity of bumper car 2 after an elastic collision, we can use the conservation of momentum and the conservation of kinetic energy principles.
Step 1: Conservation of Momentum
The formula for conservation of momentum is:
Where:
-
(mass of car 1) -
(initial velocity of car 1) -
(mass of car 2) -
(initial velocity of car 2, negative because it moves west)
Step 2: Conservation of Kinetic Energy
The formula for conservation of kinetic energy is:
Step 3: Solving for Final Velocities
Using both equations together and simplifying will yield the final velocities.
After carrying out the calculations (omitting intermediary steps for brevity):
The final velocity of car 2,
, is approximately
to the east.
