Homework Statement
A steel ball is released at the surface of the ocean and it takes 64 minutes for it to hit the bottom. The balls downward acceleration is a=0.9g-cv where g=9.82 m/s2 and c = 3.02s-1 and v is the speed. What is the depth of the ocean where the ball was released?
Homework Equations
The Attempt at a Solution
The ball will reach a top speed when v=(0.9g)/c
I am having trouble finding an expression for v with respect to time while the ball is accelerating since a depends on v.
When I am integrating a I don't know what to do with the -cv term to get an expression that depends on time
