A 7.60×103 kg transport truck is approaching a 20.0° icy hill that has a bridge at the top that is out of service. The driver immediately slams on the brakes and begins to skid up the hill. The coefficient of kinetic friction between the tires and the hill is 0.350. If there is only 131 m from the bottom of the hill to the bridge what maximum speed can the truck initially be going and still avoid an accident?
