A mass of 9kg is lifted through a height of 17 meters. How much work is performed during lifting

To calculate the work performed during lifting, we can use the formula:

Work = force * distance

First, we need to calculate the force applied to lift the mass. The force is equal to the weight of the object, which can be calculated using the formula:

Force = mass * gravitational acceleration

Gravitational acceleration on Earth is approximately 9.8 m/s^2.

Force = 9 kg * 9.8 m/s^2 = 88.2 N

Now that we have the force, we can calculate the work:

Work = 88.2 N * 17 m = 1499.4 Joules

Therefore, 1499.4 Joules of work is performed during lifting.
