Question

I already solved part a) I need help with b). I don't clearly have a clue in how to start the problem. please show me the steps to follow.

An object of mass m is thrown directly upward fromthe surface of the earth with velocityvo. Assume that the acceleration due togravity has the constant value g and that the forcedue to air resistance is equal to c times the fourth powerof the velocity.

(a) Find the maximum height attained by the object?

(b) From what height must an object of mass m bedropped in order to achieve an impact velocity ofvo?

Explanation / Answer

since u have done the first part i will telll u the approach if u solve the differential equation for the motion u will get the velocityas a function of time then substituting the final velocity v0 in the equation u will getthe time and integrate the v(t) wrt time u will get the height
