A 34,000-pound truck is parked on a 10° slope. Assume the only force to overcome is that due to gravity. Find the force required to keep the truck from rolling down the hill and the force perpendicular to the hill. (Round your answers to one decimal place.) (a) Find the force required to keep the truck from rolling down the hill. (b) Find the force perpendicular to the hill.
A 5400 -pound sport utility vehicle is parked on an $18^{\circ}$ slope. Assume the only force to overcome is that due to gravity. Find (a) the force required to keep the vehicle from rolling down the hill and (b) the force perpendicular to the hill.
