- on 14 A force of 403.0 N is exerted on a 1,250 N car while moving it a et ered distance of 2.69 m. How much work (in kJ) was done on the car? ed out ofIf the Skater was 50 kg,I.calculate the potential energy when the Skater was at the top of the left edge. which was6 metersII.calculatethe potential energy of the Skaterat themaximum point reachedby theSkater on the right side of the ramp. which was 4 metersIII.Calculate the change in potential energy between the two pointsplease asap working doesnt have to be perfect
