A small rock moves in water, and the force exerted on it by the water is given by Eq. (5.7). The terminal speed of the rock is measured and found to be 2.0 m/s. The rock is projected upward at an initial speed of 6.0 m/s. You can ignore the buoyancy force on the rock.
(a) In the absence of fluid resistance, how high will the rock rise and how long will it take to reach this maximum height?
(b) When the effects of fluid resistance are included, what are the answers to the questions in part (a)?
