Neither, they both hit the ground at the same b. The horizontally thrown ball c. The dropped ball time. 12. Friction is a force that always acts a. perpendicular to an object's motion. b. opposite to an object's motion. c. in the same direction as an object's motion. 13. The weight of a person can be represented by a vector that acts a. in a direction that depends on where the c. parallel to the ground. d. straight down, even if the person is standing person is standing. b. perpendicular to the ground underneath the on a hill. e. all of the above person. 14. The acceleration produced by a net force on an object is a. inversely proportional to the mass of the object. directly proportional to the magnitude of the net force. c. in the same direction as the net force. d. all of the above e. none of the above b.

Explanation / Answer

10. b : it would orbit earth

11. a. Neither, they both hit the ground at same time since the vertical acceleration is same

12. b: object to an objects motion

13. b. perpendicular to the ground underneath the person

14. d : all of the above.
