1. If a projectile is fired straight up at a speed of 30 m/s, the total time to return to its starting point is about *
5 points
3 seconds.
6 seconds.
30 seconds.
60 seconds.
not enough information to estimate
2. Use the appropriate Kinematic Equations to answer the following question: While entering a freeway, a car accelerates from rest at a rate of 2.5 m/s^2 for 12 s. a) How far does the car travel during those 12 s? b) What is the car's final velocity?
3.What is the acceleration of a the BMW i8 Roadster that goes from 0 to 60 mph in 3.8 seconds? a) in mi/h/s and b) in m/s^2
4. You toss a volleyball at 10 m/s straight upward. a) Draw a sketch of the scenario. b) How long will it take to reach zero speed at the top of its path? c) How long will it take to return to its starting point. d) How fast will it be going when it returns to its starting point.
5. What is the hang time of a person who can jump a vertical distance of 0.86 m?
