Your giant Chevy Silverado truck ran out of gas on a hill. The gas station is at the top of the slope. If each of your friends can apply 755.0 N of force, how many friends will you need to get the truck started up the hill? The slope of the hill is 12 degrees, the truck's mass is 1,200 kg and the coefficient of static friction is 0.56. (Important: this is static friction)
-
Fa = m*g*(sinΘ + µcosΘ) = 8886.73 N
Nf = Fa/755 = 11.77 friends
