Assuming a student pushes a 51. 5 kilogram bookshelf across a smooth floor with a net force of 67 n the acceleration is 1.30m/s².
<h3>Acceleration</h3>
Using this formula
Acceleration= Net force/Mass of bookshelf
Where:
Mass of bookshelf =51.5 kilogram
Net force =67 Newton
Let plug in the formula
Acceleration=67n/51.5 kilogram
Acceleration=1.30 m/s²
Inconclusion the acceleration is 1.30m/s².

Since n is 4 and n is 2 i belive it could be 6
Using the together rate, it is found that they would have finished the task in 8 days working together.
<h3>What is the together rate?</h3>
It is the sum of each separate rate.
In this problem, the rates are given as follows:
- Greg works four times as slower as Reid, that is, one security audit takes 40 days, hence his rate is of 1/40.
Then, the together rate is given by:
5x = 40
x = 8
They would have finished the task in 8 days working together.
