Chapter 3.2, Problem 12PP

To determine

The net force acting on a dragster.

Answer to Problem 12PP

The net force acting on a dragster is $28800.0\text{N}$ .

Explanation of Solution

Given info:

Mass of dragster, $m=900\text{kg}$

Acceleration of dragster, $a=32.0\text{m}/{\text{s}}^{\text{2}}$

Formula used:

Write the expression to calculate the acceleration using the second law of motion.

  $\begin{array}{c}a=\frac{F_{net}}{m}\\ F_{net}=m\times a\end{array}$

Here,

• $m$ is the mass of the dragster.
• $F_{net}$ is the net force.
• $a$ is the acceleration.

Calculation:

Substitute the given values in the above equation.

  $\begin{array}{c}{F}_{net}=900\times 32.0\\ =28800.0\text{N}\end{array}$

Conclusion:

Hence, the net force acting on the dragster is $28800.0\text{N}$ .
