1. During a free kick (the ball is not moving previous to being struck) a soccer ball is kicked upward at a 40 degree angle (relative to the ground) with an initial velocity of 30 m/s. The players foot makes contact with the ball for only .23 seconds. Ignoring the effects of air resistance, how far will this ball travel before it again strikes the ground?

2. As projection height increases, and everything else is held constant, what else increases? Check all that apply.

Horizontal velocity

Apex height

Horizontal distance

Vertical velocity

Total time of flight

3. A baseball is hit from 2.2 meters above the ground in the air at 25 m/s. The baseball has a projection angle of 30 degrees. How high above the ground is the baseball when it reaches its peak height?
