3 0

1 m/s^2

Using F=ma,

7=7a

a=1

<h2>Answer:</h2>

<u>The correct choice is </u><u>1 m/s2</u>

<h2>Explanation:</h2>

According to the unitary method if a force of 1 N will cause a mass of 1 kg to have an acceleration of 1 m/s2.

Then obviously force of 7 N applied to a mass of 7 kg will also cause the acceleration of the same rate which will be 7m/s^2

Or

we can use the Newtons law

F = m a

7 = 7 * 1

= 1
