16. Tony Hawk pushes his foot off the ground with a force of 120N. The skateboard experiences an overall resistance "drag" (friction on wheels and air resistance combined) of 80N. a. Draw an FBD of Tony Hawk. b. Determine the net force on Tony Hawk while he's pushing off (show all steps starting with Fnet=ma). c. From the net force we know that Tony Hawk is (speeding up, slowing down, staying at the same speed).d. After the push, draw an FBD of Tony Hawk. e. Determine the net force on Tony Hawk while he's coasting (show all steps)
