Q. A 75 kg meteorite buries itself 5.0m into soft mud. The force between the meteorite and the mud is given by F(x) = (640 N/m^3)x^3, where x is the depth in the mud. What was the speed of the meteorite when it initially impacted the mud?

Q. A car of mass 2100 kg collides with a truck of mass 4500 kg, and just after the collision the car and truck slide along, stuck together. The car's velocity just before the collision was < 32, 0, 0 > m/s, and the truck's velocity just before the collision was < -16, 0, 25 > m/s.

(a) What is the velocity of the stuck-together car and truck just after the collision?

(b) In your analysis in part (a), why can you neglect the effect of the force of the road on the car and truck?

The road doesn't exert forces on the car or truck and doesn't affect the vehicles.

Short collision time, negligible impulse compared to large impulse acting between car and truck.
