How much work is needed to lift a 400kg engine upward 1.5 meters out of a car?

To calculate the amount of work needed to lift the engine, we need to know the weight of the engine and the height it is being lifted. In this case, the weight of the engine is given as 400 kg, and the height it is being lifted is 1.5 meters.

The formula to calculate work is: Work = Force × Distance

In this case, force is equal to the weight of the engine, which is given by the formula: Force = mass × acceleration due to gravity.

Acceleration due to gravity is typically taken as 9.8 m/s². So, the force required to lift the engine is: Force = 400 kg × 9.8 m/s².

Now, we can calculate the work: Work = Force × Distance. Plugging in the values, we have:

Work = (400 kg × 9.8 m/s²) × 1.5 meters

Calculating this equation, we find that the work needed to lift the 400 kg engine upward by 1.5 meters is 5,880 Joules.
