Newton's second law of motion is F = ma.

A net force of 60 N north acts on an object with a mass of 30 kg. Use Newton's second law of motion to calculate the amount of acceleration the object will experience. Then explain how the amount of acceleration will change if the net force or the mass of the object increases.

Answers

Answer:

this was asked before here the screenshot

If F=ma then A= f/m so 60 divide 30 = 2
If force increases then acceleration will increase too example 90/30=3
But if mass increases acceleration decreases example 60/60 =1

Answers

Answer: B) two children pulling apart a wishbone

One person is on the left side, and the other person is on the right side. They pull in opposite directions to separate the bone. These forces counteract each other since they go in opposite directions.

In contrast, each of choice A, C, and D describe one or more forces that work together to go in the same direction. This could be a pulling force, or a pushing force, it doesn't matter either way. We can rule out choices A,C, and D for this reason.
