Question

An auto weighing 2,000 pounds is on a street inclined at 10° with the horizontal. Find the force necessary to prevent the car from rolling down the hill. (Round your answer to the nearest whole number.)

347 pounds
14,397 pounds
2,462 pounds

Answer 1

Force (F) = WSin(angle)

F = 2000×Sin(10)

Therefore, F = 347lb.
