SUMMARY
The minimum work required to push a 1770 kg car up a 16.2-degree incline with a coefficient of friction of 0.25 is calculated using the formula for frictional force and gravitational force. The normal force (FN) is determined to be 16657 N, leading to a frictional force (Ff) of 4164.25 N. The gravitational force component acting down the incline is 4839 N. The total work done against both friction and gravity must be calculated by summing these forces and multiplying by the distance of 346 m.
