Question

You have completed various experiments with both 50 and 80 kg masses. If you were to complete the above simulation with a 150 kg mass, how much force would be required to move the load?

Answer 1

20

Explanation:

if you already completed various experiments with 50 and 80, add those 2 and you get 130. Then just subtract 150 and 130 and you should get 20.

please let me know if this is correct, i didn't really understand the question that well but this is what seems correct from the way i am looking at it.

hope this helps!!
