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.
4. In the Y= Editor , enter the equation for the
height of the ball at time t for yt1(t) .
yt1(t)= L 16 † t^2+95 † t † sin(32 ¡ )
