9-10. Calculate the displacement and velocity at times of (a) 0.500, (b) 1.00, (c) 1.50, and (d) 2.00 s for a ball thrown straight up with an initial velocity of 15.0

m/s. Take the point of release to be y₀ = 0 .

11. Determine your reaction time by having a student drop a ruler between two fingers, and you catch it. Using the constant acceleration due to gravity and the distance it travelled which is measurable then the time is something that can be calculated.

12. If you go down the on ramp onto an interstate starting from a velocity of 0, and end up at 70 mph in 10 seconds, what is your acceleration (in ft per second squared)? If 1 G = 32 fps², how many Gs is that?

13. Proceeding down the interstate, at 70 mph you, swerve to miss a slow driver, and hit a guardrail. Your car and your body comes to a complete stop in 15 feet, what is the deceleration in fps² and how many Gs is that?
