At one instant in time, a rock falling off a cliff experiences an upward force from air resistance at a magnitude of 10 n. the rock itself has a mass of 7 kg. what is the magnitude and direction of the acceleration of the rock at this instant? (take the magnitude of acceleration due to gravity to be 9.8 m/s2 and indicate direction by using a value for downward and a (+) value for upward.)
(hint: what is the net force acting on the rock? )
note: be careful entering your units! follow the instructions in the guide posted in the homework section!
