A two-inch diameter craft ball is thrown vertically. This initial velocity of the ball is 20 ft/s

a) Neglecting drag, draw a free body diagram and formulate a first order ODE that governs the velocity of the ball. Is the ODE linear or non-linear?
for part a I got t= 0.62 second

b) To determine the drag coefficient effect, an experiment has been conducted that showed the terminal velocity of the ball (during a free fall) to be 20 ft/s. Use Euler’s method to estimate the "actual" time to achieve maximum elevation for the case that the ball is thrown up with the given initial velocity (20 ft/s).
