- 17. Multiple ChoiceProblem #3
A car is traveling at a velocity of 35.0 miles per hour. The car runs off a cliff that has an unknown height. The car 'lands' 50.0 meters from the base of the cliff.
How long would it take the car to 'land' after exiting the rim of the cliff?1.4 seconds3.2 seconds4.8 seconds0.7 seconds - 18. Multiple ChoiceBeau throws a baseball at 23.0 m/s at an angle of 25.0 degrees relative to the ground.If the ball was caught 42.0 m from Beau, find the componentsVx=20.8 m/s
Vy=9.72 m/sVx=9.72 m/s
Vy=20.8 m/sVx=20.8 m/s
Vy=19.72 m/sVx=19.8 m/s
Vy=9.72 m/s - 19. Multiple ChoiceBeau throws a baseball at 23.0 m/s at an angle of 25.0 degrees relative to the ground.If the ball was caught 42.0 m from Beau, find the time the ball was in the air0.991 seconds1.52 seconds1.98 seconds2.05 seconds
- 20. Multiple ChoiceBeau throws a baseball at 23.0 m/s at an angle of 25.0 degrees relative to the ground.If the ball was caught 42.0 m from Beau, the maximum height the ball reached2.81 m4.81 m8.81 m12.81 m
