A mechanical jack is used to lift a car.(i) (1 mark)If a 1300 kg car is raised 0.28 m, how much work was done on the car?(ii) (1 mark)If the lever was pushed a total distance of 5.1 m at constant force, how large was the force applied? Assume 100% efficiency.(iii) (3 marks)Now suppose the jack is only 60% efficient. The person operating the jack supplies 75 W of power. How long does it take to lift the car the 0.28 m distance?
