Using the v2 form of drag write a program to determine how

Question

You need to solve these equations

Question: 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.

Suppose 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 = ½ rAC using these three equations

a)  x=x + v(dt)+1/2a(dt)^2

b) v=v +a(dt)

c) t=t+dt

Please show me all the working and provide the answer.
