- 6. Multiple Choice
The diagram represents the path of a car that is driven off a cliff. Neglecting air resistance, the horizontal component of the velocity at A is _______ the horizontal component of the velocity at Bsmaller thangreater thanthe same ascan not be determined - 7. Multiple ChoiceAccording to the picture, which points is the speed of the projectile the same?B and EA and EB and DBoth A and E, B and D
- 8. Multiple ChoiceIn the absence of air resistance, the angle at which a thrown ball will go the farthest is?60 degrees45 degrees15 degrees30 degrees
- 9. Multiple ChoiceThe cannon fires at 45 degrees with a set velocity. If the angle of the projectile is raised to 75 degrees, what would happen to the height and range of the projectile's path?The projectile would travel to a greater height and have a longer range.The projectile would travel to a lower height and have a smaller range.The projectile would travel to a greater height and have a smaller range.The projectile would travel to a greater height and have the same range.
- 10. Multiple ChoiceA ball is thrown straight upward at 20 m/s. With no air resistance, the ball will return to the thrower's hand with a speed of?20 m/s40 m/s80 m/s0 m/s
- 11. Multiple ChoiceThe picture shows two objects that were dropped and recorded with a stroboscopic camera. The best explanation for the results is that object Ahas less air resistancewas dropped from a greater heighthas a smaller massaccelerated more slowly
