Chapter 3.2, Problem 11PP

To determine

The acceleration of the helicopter.

Answer to Problem 11PP

The acceleration of the helicopter is $1500\text{m}/{\text{s}}^{\text{2}}$ .

Explanation of Solution

Given info:

Maasof helicopter, $m=4500\text{kg}$

Net force acting on helicopter , $F_{net}=18000\text{N}$

Formula used:

Write the equation for the acceleration using the second law of motion.

  $a=\frac{F_{net}}{m}$

Here,

• $m$ is the mass.
• $F_{net}$ is the net force.

Calculation:

Substitute the given values in the above equation.

  $\begin{array}{c}a=\frac{18000}{12}\\ =1500\text{m}/{\text{s}}^{\text{2}}\end{array}$

Conclusion:

Hence, the acceleration of the helicopter is $1500\text{m}/{\text{s}}^{\text{2}}$ .
