Question

Which expression shows the amount of work a 6-kilogram mass is capable of performing if it is dropped from a height of 2 meters? The acceleration of gravity is .

Answer 1

To answer this question you need to know that work = force x distance. You know the distance is 2m. Weight is a force and you can find that with the information given.
Weight = mass x gravity
In this case we're taking about acceleration of gravity which equals 9.8m/s/s
Weight = 6kg x 9.8m/s/s
W= 58.8 newtons or kg-m/s/s
So now that you know force and distance you can find work
Work= force x distance
Work = 58.8 newtons x 2 meters
Work = 117.6 n-m or joules
Hope this helps!

Answer 2

The acceleration of gravity is 9.8 m/s^2
