Some Momentum Problems

1) A 2698 kg pick-up truck driven by Ford Tuff has a velocity of 42.4 m/s east. What is the magnitude of the momentum of the truck in kg-m/s?
2) A 2198 kg police pursued van is driven by Chase Mee. The van exhibits a momentum of 3698 kg-m/s. What is the velocity of the van in m/s as it veers rightward into a guardrail?
3) Rocky Surface, an astronaut with a mass of 105 kg, wears a space suit with a mass of 42 kg. If Rocky walks on the moon at a rate of 4 m/s eastward, what is the magnitude of the momentum of the astronaut and his suit in kg-m/s?
4) Rocky the astronaut from the problem above decides to run around on earth (6 times the acceleration due to gravity as compared to the moon) in his space suit with a velocity of 4 m/s westward. What would be the magnitude of the momentum in kg-m/s?
5) A force of 674 N is applied to a 4047 kg object for 31.9 seconds. What is the change in velocity that the object experienced?
6) P. Lise Go pushed her 779 kg vehicle from rest to 3.7 m/s in 21 seconds. What is the magnitude of the impulse on the car? (No + or - signs.)
7) Lee Mealone, a hermit, pushes a 16985 gram boulder into the wall of his cave at a speed of 4.5 m/s, the boulder is brought to a stop in 1.6 seconds. What was the magnitude of the average force in Newtons of the boulder on the wall? (No + or - signs.)
