Chapter 3, Problem 24A

Calculate in newtons the weight of a 2000-kg elephant.

To determine

The weight of an elephant in newtons.

Answer to Problem 24A

  $W=1.96\times {10}^4\text{ N}$

Explanation of Solution

Given:

Mass of an elephant $m=2000\text{ kg}$

Formula used:

Weight of an elephant can be calculated using the equation,

  $W=mg$$\left(1\right)$

Where, $m$ is mass of an elephant,

$g$ is acceleration due to gravity, $g=9.8{\text{ m/s}}^2$

Calculation:

Substituting the numerical values in equation $\left(1\right)$ ,

  $W=\left(2000\text{ kg}\right)\left(9.8{\text{ m/s}}^2\right)$

  $=19600{\text{ kgm/s}}^2$

  $=1.96\times {10}^4\text{ N}$

Conclusion:

The weight of a given elephant in newtons is $1.96\times {10}^4\text{ N}$ .
