The object of interest for the situation described in the problem introduction is a piano.
An acceleration can be defined as the rate of change of the velocity of an object with respect to time.
Mathematically, acceleration is given by this formula:
[tex]a = \frac{V\;-\;U}{t}[/tex]
Where:
Based on the situation, you should draw a free-body diagram for the piano with respect to its:

Situation:
Chadwick is pushing a piano across a level floor (see the figure). The piano can slide across the floor without friction.
