**Title:** ** Softball Toss**

**Objectives: **Using time, distance, g, and vector analysis,
determine velocity of ball thrown into air.

**Materials:**
softball, stopwatch, football field.

NOTE: Each “team” has 1 thrower, 2 timers (1 optional
spotter)

**Methods**

1. Prepare
your lab data sheet to record **your**
throw:

a.
total time in the air to 0.1 seconds based on an average
of the two timers.

b. the horizontal distance accurate to 1
meter (throw must be perpendicular to goal line)

2. Throw the
softball 10 - 20 m to maximize "hang time." Use a high
angle of throw.

* Analysis of your throw*:

1. Using the motion equations and your data for time and distance, determine the vertical & horizontal velocities and the maximum height of the ball.

2. Using graphical vector analysis (i.e., 1.0 cm = 1.0 m/s), draw to scale the vertical velocity component and the horizontal

3. In the absence of air resistance, predict & explain the ideal angle to maximize horizontal distance.

4. Determine the following for your throw:

a) g at the maximum height of the throw.

b) the velocity of the ball at just prior to impact.

c) the vertical and horizontal velocities
