Activity #1: 1. To begin with, you will be asked to throw a ball in the air.

a. throw of the ball, from release to the peak, to catching it again.

b. Throw the ball in the air so that it reaches a decent maximum height. Roughly more than a meter but less than 10 meters. .

c. Throw the ball straight up in the air, not sideways at all. You should catch the ball at the same height at which you threw it.

d. Repeat the procedure a few times, to make sure you get a clean throw. Record each throw and pick the best for analysis.

2. record the time from the moment the ball leaves your hand. Then make note of the time right before the ball comes back to your hand. Find the time of flight of the ball and write out all your work below.

Answer 1st 1.31second - 2nd 1.35sec - 3rd 1.38sec

3. Making some assumptions about the initial and final velocities, derive an equation for finding the velocity from the time of flight you measured in #2. Write out all your work.

(HINT: v0 = -vf)

4. From the information you have, derive the maximum height of the ball you threw. Write out all the work in the space below.

5. estimating a scale, comment on how accurate your calculation of maximum height is. Write out all your work and assumptions, i.e. using your height, you estimate the height of the ball to be twice your height).

6. In the space below, sketch a graph of the position versus time, velocity versus time, and acceleration versus time of the ball's flight. . Below each sketch, explain your choice of graph shape.
