Example The path over time T off a ball thrown in the air at initial velocity V and
an angle of
θ
degrees from horizontal can be calculated as follows.
X = (Vcos
θ
)T, Y = (Vsin
θ
)T – (1/2)gT

(g = 9.8m/s

)
Use Dynamic Graph to plot the path of a ball thrown at an initial
velocity of 20 meters per second, at horizontal angles of 30, 45, and 60
degrees (Angle: Deg).
Use the following V-Window settings.
Xmin = –1, Xmax = 42, Xscale = 5
Ymin = –1, Ymax = 16, Yscale = 2
