Solve the problem.The differential equation for a falling body near the earth's surface with air resistance proportional to the velocity v is  where g = 32 feet per second per second is the acceleration due to gravity and a > 0 is the drag coefficient. This equation can be solved to obtain  v(t) = (v0 - v?)e-at + v?, where v0 = v(0) and v? = -g/a = v(t), the terminal velocity.This equation, in turn, can be solved to obtain  y(t) = y0 + tv? + (1/a)(v0 - v?)(1 - e-at) where y(t) denotes the altitude at time t. Suppose that a ball is thrown straight

up from ground level with an initial velocity v0  and drag coefficient a. Find an expression in terms of v0, g, and a for the time at which the ball reaches its maximum height.
