  1. How far will a 4320 N car with a momentum of 345 kgm/s roll in 22 sec?

  2. If you want to increase the velocity of an object of mass 875 kg by 35 m/s how long must you apply a 43 N force.

  3. Two cars hit each other and their bumpers stick together. If the first car weighs 7430 N and was traveling at 15 km/hr and the second car weighs 6460 N and was traveling the opposite direction at 95 km/hr when they hit, how far will they roll if a frictional force of 346 N acts on them after the accident?

  4. A rocket sled on a frictionless track has a mass of 1.4 X 104 kg. For propulsion, it expels gases from its rocket engines at a rate of 10 kg/s at an exhaust speed of 2.5 X 104 m/s. For how long must the engine burn in order that the sled reach a velocity of 50 m/s starting from rest? (ignore any change in mass of the sled as it burns fuel)

  5. Two men (each with a mass of 100 kg) are on a cart (mass = 300 kg) on a frictionless track at rest. One man runs to the north and jumps off at a speed on 5 m/s relative to the cart. After he jumps the second man runs to the south and jumps off of the cart with a speed of 5 m/s relative to the cart. What is the speed and direction of the cart after both men jump off.

  6. Tarzan (m = 75 kg) is hanging straight down from a vine (l = 30 m). A monkey (m = 25 kg) is going to jump from a nearby tree onto Tarzan causing him and the monkey to swing back to an angle of 30o with the vertical. What was the monkey’s initial horizontal speed?
