A car drives 150 m on a road that is inclined 12° to the horizontal. The car weighs 11 000 N. Thus, gravity acts straight down on the car with a constant force F = - 11 000 j. Find the work done by the car in overcoming gravity.
work = PE gained = mgh = 11000 * 150 sin12° = _____ J
force is not measured in Joules, but Newtons
