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.

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
