Please answer the following questions

16. A rock is dropped into a deep shaft in a cave, the time until it is heard hitting the bottom is recorded. Which equation is the best choice to determine how deep the shaft is? (A) vr= vit at (B) d= 1/2 (vetvi)t (C) d= 1/2 at2 + vit (D) v? = vi + 2ad (E) d = vt 17. Which equation is best suited to determine how long it will take a radio signal to get from Earth to the Mars Rover and back? (A) vr= vit at (B) d= 1/2 (vf+vi)t (C) d = 1/2 at + vit (D) vr = vi + 2ad (E) d = vt Use the following rockets to answer questions 18 -19. (A) Rocket A is traveling at 330-m/s, and has a mass of 2-kg. (B) Rocket B is traveling at 200-m/s and has a mass of 1-kg. C) Rocket C is traveling at 300-m/s and has a mass of 0.5-kg. 18. A series of rockets are launched from the surface of the earth. At 200-m above the surface, the engines shut off. Which rocket will go the highest? 19. Which rocket will take the longest to come back down to the ground? 20. Which equation is the best option to determine the time for the rocket to return to the ground (assume no parachute). (A) vr= vit at (B) d= 1/2 (vf+vi)t (C) d = 1/2 at + vit (D) ve = vi + 2ad (E) d = vt Graphs: Analyze the following graphs. 21. What is the distance traveled from 0-10 sec? P VS T 22.
