  1. ICP Chpt 11-12 Quiz Review 1/31/13

  2. Warmup • Two ice skaters stand together at rest on the ice. They push off of each other. Ice Skater A is 100 kg and pushes away with a velocity of 3 m/s. Ice Skater B is 60 kg. What is the velocity of Ice Skater B?

  3. Quiz Prep assignment • P415 (1-2) • P423 (21-23)

  4. P415 and 423 1) Calculate the momentum. a) 75 kg speed skater moving forward at 16 m/s b) 135 kg ostrich running north at 16.2 m/s c) a 5.0 kg baby on a train moving eastward at 72 m/s d) A 48.5 kg passenger seated on a train that is stopped

  5. 2) Calculate the velocity of a 0.8 kg kitten with a forward momentum of 5 kg m/s.

  6. 21) A student tests the second law of motion by accelerating a block of ice at a rate of 3.5 m/s2. If the ice has a mass of 12.5 kg, what force must the student apply to the ice?

  7. 22) A bag of sugar has a mass of 2.26 kg. What is its weight in newtons on the moon, where the acceleration due to gravity is one-sixth of that on Earth? (Hint: On Earth, g = 9.8 m/s2.)

  8. 23) Calculate the momentum of the following objects: a) A 65 kg skateboarder moving forward at the rate of 3 m/s. b) A 20 kg toddler in a car traveling west at the rate of 22 m/s c) A 16 kg penguin at rest
