1) Half of the team decided not to pull the airplane the combined force of those left is $4500\ N$ while the airplane mass is still $30,000\ kg$. what will be the acceleration?
2) A girl pulls a wheeled backpack with a force of $3\ N$ if the backpack has a mass of $6\ kg$. What is acceleration?
1). Here, mass $m=30,000\ kg$
Force $F=4500\ N$
Therefore, acceleration $a=\frac{4500}{30,000}$
$=0.15\ m/s^2$
Therefore, acceleration is $0.15\ m/s^2$
2). Here, force $F=3\ N$
Mass $m=6\ kg$
Therefore, acceleration $a=\frac{F}{m}$
$=\frac{3\ N}{6\ kg}$
$=0.5\ m/s^2$
