A small rock moves in water, and the force exerted on it by the water is given by equation f=kv. The terminal speed of the rock is measured and found to be 1.6m/s . The rock is projected upward at an initial speed of 6.7m/s . You can ignore the buoyancy force on the rock. How high will the rock rise?
