How much work is done lifting a 1.70 kg box straight up onto a shelf that is 17 m high

Answer 1

To find the work done in lifting the box, we need to use the formula:

Work = force × distance

The force exerted to lift the box is equal to its weight, which can be calculated using the formula:

Weight = mass × acceleration due to gravity

Assuming that acceleration due to gravity is approximately 9.8 m/s², we can calculate the weight to be:

Weight = 1.70 kg × 9.8 m/s² = 16.66 N

Now we have the weight and the distance (17 m), so we can calculate the work:

Work = force × distance = 16.66 N × 17 m = 283.22 J

Therefore, the work done in lifting the 1.70 kg box straight up onto a shelf that is 17 m high is approximately 283.22 Joules.
