Questions 7 & 8 refer to the following diagram and situation: Two spheres of the same shape (A and B) are projected off a 2.0 m high table with the same horizontal velocity. Sphere A has a mass of 10 g. Sphere B has a mass of 5 g. X 7. If both spheres leave the edge of the table at the same instant, which sphere will land first? a. Sphere A b. Sphere B c. Both will land at the same time d. There is not enough information to decide 8. If both spheres leave the edge of the table at the same instant, which sphere will travel further before hitting the ground? a. Sphere A b. Sphere B c. Both will land at the same location d. There is not enough information to decide 9. Starting from rest, after 10 seconds, a freely-falling object will travel a vertical distance of about... a. 9.8 m. b. 49 m. c. 98 m. d. 490 m. 10. When a rock thrown straight upward gets to the exact top of its path, the magnitude of its a. Velocity is zero and its acceleration is zero. b. Velocity is zero and its acceleration is about 9.8 m/s' pointing downwards. c. Velocity is about 9.8 m/s and its acceleration is zero. d. Velocity is about 9.8 m/s and its acceleration is about 9.8 m/s' pointing downwards. 11. Suppose a rescue plane drops a relief package while it is moving with a constant horizontal speed at an elevated Drop Point height. Assuming that air resistance is negligible, where will the relief package land relative to the plane? a. Behind the airplane (labeled A) b. Exactly below the airplane (labeled B) c. Ahead of the airplane (labeled C) d. More information is needed to answer the
