Question

Determine the object of interest for the situation described in the problem introduction. For this situation you should draw a free-body diagram for.

Answer 1

The object of interest for the situation described in the problem introduction is a piano.

What is an acceleration?

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:

$a = \frac{V\;-\;U}{t}$

Where:  

• V is the final velocity.

• U is the initial velocity.

• t is the time measured in seconds.

Based on the situation, you should draw a free-body diagram for the piano with respect to its:

1. Weight.
2. Normal force
3. The pushing force by the pusher (Chadwick).

Situation:

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