Studying the Flight of a Hit Baseball
This activity uses the split screen settings to show a parametric graph and a table at the
same time to study the flight of a hit baseball.
Setting Up a Parametric Graph and Table
Perform the following steps to study the flight of a hit baseball that has an initial velocity
of 95 feet per second and an initial angle of 32 degrees.
1. Set the modes for
Page 1 as shown in this
screen.
2. Set the modes for
Page 2 as shown in this
screen.
3. In the
Y= Editor on the left side, enter the
equation for the distance of the ball at
time
t for xt1(t).
xt1(t)=95†t†cos(32¡)
Note: Press 2 “ to obtain the degree
symbol.
