Answer:

0.6... or 3/5

Explanation:

To find the acceleration, we need to use the acceleration formula:

  • a=F/m

So all we have to do now is plug in the numbers:

  • a = 60/90

Once we divide 60 by 90, we will get the acceleration of the marble.

  • 60/90 = 0.6... (repeating)

Our final answer should be:

0.6... or 3/5
