A skateboarder rolls down a 10° incline. The wheels' rolling resistance can be treated like friction with a coefficient of 0.07. a. At what rate will the skateboarder accelerate down the incline? b. If we add the air resistance force with magnitude in Newtons is given by F(v) = 0.5v², what is the top speed the skateboarder will hit given that the incline is sufficiently long to achieve top speed?
