Very important: please don't give me answersI don't need thatI need explanationsAll help appreciated.1A forklift lifts a 4050 kg mass in the airThe amount of work that must be done by the forklift's lifting components is 4.5x10 to the power of 5 J(10 is to the power of 5)If the efficient of the crane is 34%, how much useful work is done on the mass?Note: 4.5x10 to the power of 5 450000 joules2A motor cycle engine is able to do 4455 J of useful workIf the engine has an efficiency of 25%, what is the amount of work that must be done on in the engine to allow it to work?3Thomas the tank engine is 35% efficientIf the useful work done each second by Thomas is 5.33x10 to the power of 6 J (10 is to the power of 6), how much work did Thomas input?Note: 5.33x10 to the power of 6 5330000 JThanks so much!
1Force (in newtons) to lift anything mass (kg) X g g gravitational accelof 9.8 m/s^2 Work done (in joules) on the object being lifted Force X distance Work output (useful work) / Work input (machines work) X 100 efficiency 2again Work output (useful work) / Work input (machines work) X 100 efficiency sub in the numbers and rearrange to find the answer 3same formula subrearrange using algebra
