A valuable antique chest which weighs 1400 N is to be moved into a truck. To get the chest from the ground onto the truck bed, which is 1.0 m higher, the movers push it up a rough ramp 4.0 m in length.
The coefficient of kinetic friction between the chest and the ramp is 0.20. Calculate the work done by the
movers on the chest if they push it at constant speed with a force, F, at an angle of B = 30° above the

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
