12 m/s/s

Answer: 12 m/s/s The original value of 2 m/s/s must be multiplied by 3 (since a and F are directly proportional) and divided by 1/2 (since a and m are inversely proportional)

The answer to this is 12 m/s/s. In order to get this answer, you need to check out the given numbers first. The accelerating rate is at 2 m/s2. This has to be multiplied by 3 because the acceleration and force are directly proportional to each other.

Take note that you still have to consider the mass which is inversely proportional to acceleration. The answer will be divided by 1/2. This brings the answer to 12 m/s/s. You should rearrange the formula for Force which is F=ma. Once you have made some rearrangements, you will have the formula for acceleration. Divide the number that you will get with the mass of the object.
