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:

$+2700$
