A rocket in deep space has an empty mass of kg and exhausts the hot gases of burned fuel at m/s. What mass of fuel is needed to reach a top speed of m/s?
A 2100 kg truck is traveling east through an intersection at 2.0 m/s when it is hit simultaneously from the side and the rear. (Some people have all the luck!) One car is a 1200 kg compact traveling north at 5.0 m/s. The other is a 1500 kg midsize traveling east at 10 m/s. The three vehicles become entangled and slide as one body. What are their speed and direction just after the collision?
