Using the v² form of drag, write a program to determine how long (sec.) and how far (m) a 150 gram ball whose radius is 3.5cm would fall before it reached 75% of its terminal velocity. Assume ball falls in air whose density is 1.21 kg/m³, has a drag coefficient C = .3, cross-sectional area is just the disk a sphere presents to the eye. Your answer should be good to 1%. (How will you know?) Recall D = Â½ rAC

using these three equations

1) x=x + v(dt)+1/2a(dt)^2

2) v=v +a(dt)

3) t=t+dt
