The steel of the motorcycle rubs against the concrete road surface. (a) what is the frictional force between the road and the motorcycle/rider? (b) what would the acceleration of the motorcycle and rider during the wipeout? (c) assuming there were no barriers to stop the motorcycle/rider, how long would it take the bike to slow to a stop? (d) using the acceleration found in (b), if the motorcycle and rider have been sliding for 5.23 s, what will be the force applied to the motorcycle and rider when they strike the side barrier and come to rest in another 0.32 s?
