Question

What is. the speed of 525-kg giraffe galloping with kinetic energy of 4200 J?

Answer 1

Given

Mass of the giraffe, m=525 kg

Kinetic energy, K=4200 J

To find

The speed of the giraffe

Explanation

let the velocity be v

We know kinetic energy is given by

$K=\frac{1}{2}mv^2$

Putting the value

$\begin{gathered} 4200=\frac{1}{2}\times525\times v^2 \\ \Rightarrow v=\frac{4m}{s} \end{gathered}$

Conclusion

The speed is 4 m/s
