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

Step-by-step explanation

let the velocity be v

We know kinetic energy is given by

`K=(1)/(2)mv^2`

Putting the value

`\begin{gathered} 4200=(1)/(2)*525* v^2 \\ \Rightarrow v=(4m)/(s) \end{gathered}`

Conclusion

The speed is 4 m/s
