5. A fisherman reels in a Mahi-mahi straight up through the water, with a deceleration that is constant. The Mahi-mahi’s initial upward velocity is 1.00 m/s. Assume that the fishing twine passes over the reel without slipping or sliding, and assume the reel is a uniform 0.650-kg disk with a radius of 5.00 cm. The net torque on the fishing reel is —0.00390 Nm.
