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.
