How much work does gravity do on a 0.110 kg ball falling from a height of 20,9 m? (Neglect air resistance.) Need Help?
Read it

Explanation:

Work = F * d

m = 110 kg

a = 9.8 (acceleration due to gravity).

d = 20.9 m

F = m * a

F = 110 * 9.8

F = 1078 Newtons

Work = 1078 N * 20.9 m

Work = 10564.4 Joules

Below

Explanation:

To find the work done by gravity on an object, you can use this formula:

     Work = (mass)(gravity)(height)

We know that objects accelerate towards earth at a rate of 9.8 m/s^2 so

     Work = (0.11kg)(9.8m/s^2)(20.9m)

               = 22.5302 J

For this question we need to round the final answer to 3 sig figs :

     = 22.5

Therefore, the work done on the ball by gravity is 22.5 Joules

Hope this helps! Best of luck <3

use photo math tells u all the answers thats what i use
