Paolo "The Soundwave" is an amateur street luger. His mass is 85 kg, and his second-hand luge racer is 11 kg. He crossed the finish line travelling at 15 m/s and locked his rubber wheels to a create an ominous skid to the disinterest of all. He stopped in exactly 7.2 seconds. Calculate the force of friction present in this situation.
