The last few, differential equation free fall problem

The rate of change of the downward velocity of a falling object is the acceleration of gravity (10 meters/sec^2) minus the acceleration due to air resistance. Suppose that the acceleration due to air resistance is 0.2 inverse seconds times the downward velocity. Write the initial value problem and the solution for the downward velocity for an object that is dropped (not thrown) from a great height. dv dt v(0) : = 0 v(t): 10 - 0.2v = 50 - 50e-0.2t what is the terminal velocity? 5 meters/second How long before the object reaches 90% of terminal velocity? seconds How far has it fallen by that time? meters symbolic formatting help
