A car of mass 2300 kg collides with a truck of mass 4300 kg, and just after the collision the car and truck slide along, stuck
together, with no rotation. The car's velocity just before the collision was 38, 0, 0 m/s, and the truck's velocity just before
the collision was −16, 0, 27 m/s.
(a) Your first task is to determine the velocity of the stucktogether car and truck just after the collision. What system
and principle should you use?
(A) Energy Principle
(B) Car plus truck
(C) Momentum Principle
(D) Car alone
(E) Truck alone
(b) What is the velocity of the stuck-together car and truck just after the collision?
(c) In your analysis in part (b), why can you neglect the effect of the force of the road on the car and truck?
(d) What is the increase in internal energy of the car and truck (thermal energy and deformation)?
(e) Is this collision elastic or inelastic?
