a 450 kg piano has an acceleration of +6.0 m/...
a 450 kg piano has an acceleration of +6.0 m/s² when a force is exerted onto it. what is the net force acting on the piano? a = +6.0 m/s² f = ? n remember to indicate direction (+ or -) and magnitude.
Answer
# Explanation:
## Step1: Identify the formula
Use Newton's second - law $F = ma$.
## Step2: Substitute values
Given $m = 450\ kg$ and $a=+6.0\ m/s^{2}$, then $F=(450\ kg)\times(+ 6.0\ m/s^{2})$.
## Step3: Calculate the force
$F = 2700\ N$. The positive sign indicates the direction is the same as the direction of acceleration.
# Answer:
$+2700$
