A 25.0 kg bumper car moving to the right at 5.00 m/s overtakes and col-
lides clastically with a 35.0 kg bumper car moving to the right. After the
collision, the 25.0 kg bumper car slows to 1.50 m/s to the right, and the
35.0 kg car moves at 4.50 m/s to the right.
a. Find the velocity of the 35 kg bumper car before the collision.
.b. Verify your answer by calculating the total kinetic energy before and
after the collision.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
