SHORT ANSWER
30. ANS: 60ºC

31. ANS: The two cars are traveling in different directions.

32. ANS: A: 250 kg m/s; B: 12 kg; C: 12 m/s; D: 20 kg

33. ANS: Crumple the paper into a ball to reduce the air resistance.

34. ANS: They will hit at the same time. Vertically, they travel the same distance under the influence of the same force, gravity; horizontal motion doesn't count.

35. ANS: Mass measures the amount of matter; weight measures the force of gravity on the matter.

PROBLEM
36. ANS: 3.75

37. ANS: 5.675

38. ANS: s = d/t = 10 km/40 min = 0.25 km/min

39. ANS: d = s ´ y = 227 km/h ´ (2.00 h) = 454 km

40. ANS: vf – vi/t = (96 m/s – 32 m/s)/ 8.0 s = 8.0 m/s2

41. ANS: 250 kg ´ m/s p = mv = 10 kg ´ 25 m/s = 250 kg ´ m/s


42. ANS: 48 N
F = ma = 12 kg ´ 4 m/s2 = 48 kg ´ m/s2 = 48 N
