An object with mass 128 kg is given an initial downward velocity 2- in a medium that exerts a resistive force with magnitude proportional to the square of the speed. the resistance is 320 n when the 17 , use g velocity is 10 . write out a differential equation in terms of the velocity , and acceleration a a10 5/32 ( 2-64) preview . find the velocity (t) for the object v8(1-5/3" e (5ty2)y ( 1 + preview upload a document with the work for parts a and b and a computer generated solution curve with a window appropriate for this situation.
