As a result of the collision, the cars stick together, and slide off the road.
f) Write down the expression for the momentum of the combined masses after the collision.
This will be in terms of a variable.
Pr =
g) Use conservation of momentum to the magnitude and direction of the final velocity, V₁.
Magnitude of V=____
m/s
h) What is the kinetic energy of the combined masses just after the collision?
KE₁ =
Off the road, the surface is no longer frictionless, and the coefficient of kinetic friction, 4 = .3. For this
part of the problem, your answer to part h) is KE, for the sliding part.
Direction of V
i) After some sliding, the cars come to a stop. Use kinetic energy to determine how much work was done
by the non-conservative force to stop the cars?
