  18. Momentum for $500 How fast must a 0.15kg tennis ball travel to have the same momentum as a 900kg Chevy Avalanche going 20 m/s? Answer

  19. Impulse for $500 What force must a person hit a stationary 0.12kg soccer ball if the force last for .02 seconds and the ball moves with a speed of 20 m/s? Answer

  20. Inelastic Collision for $500 When a 80kg guy is roller skating at a speed of 6m/s and runs into a 40kg girl at rest, what is the velocity after the collision? Answer

  21. Elastic Collision for $500 A bowling ball of mass 6kg moving at 5m/s strikes a pin of mass 0.8kg. The pin flies off with a velocity of 10m/s. How fast is the bowling ball now moving? Answer

  22. Momentum - $100 True During rock climbing nylon ropes stretch to extend force over a period of time decreasing the force of momentum Next

  23. Impulse - $100 False The impulse of a force, F, acting on an object is equal then the product of the force and the time interval during which the force acts Next

  24. Inelastic Collision - $100 Inelastic collision is a collision in which momentum is conserved and kinetic energy non-conserved. Next

  25. Elastic Collision - $100 In an elastic collision both momentum and kinetic energy is conserved. Next

  26. Momentum - $200 D. p=mv Next

  27. Impulse - $200 Momentum Next

  28. Inelastic Collision - $200 When an object sticks together with another object Next

  29. Elastic Collision - $200 When an object collides with a 2nd object and the momentum of the 1st object to bounce off each other. Next

  30. Momentum - $300 Yes it depends on force and time of each object. Next

  31. Impulse - $300 Newtons (seconds) Next

  32. Inelastic Collision - $300 The bug will stick to the truck. Next

  33. Elastic Collision - $300 The 110lb person will bounce off the 170lb person. Next

  34. Momentum - $400 Newton’s Second Law F=ma Next

  35. Impulse - $400 f(change in time)=mvf-mvi Next

  36. Inelastic Collision - $400 C – When one freight car hits another because they stick together Next

  37. Elastic Collision - $400 B- when a pool ball hits another because the energy from the first ball is transferred to the next ball and they don’t stick together Next

  38. Momentum - $500 Givens: m=900kg v=20m/s p=mv p=900(20) p=18,000 m=.15kg v=? p=mv 18000=.15v v=120,000m/s Next

  39. Impulse - $500 F x t = m (change in velocity) F (.02sec) = .12kg (20m/s) F (.02sec) = 2.4 F = 120 N Next

  40. Inelastic Collision - $500 m1v1+m2v2= m1v1+m2v2 80(6)+40(0)=80(v)+40(v) 480=120v2 360=v2 v= 18.97 m/s Next

  41. Elastic Collision - $500 m=0.8kg v=10m/s p=mv p=0.8(10) p=8kg m/s Givens: m=6kg v=5m/s p=mv p=6(5) p=30kg m/s m1v1=m2v2 6(5)=.8(10) 30=8 30-8= 22kg m/s Next
