Answer:
[tex]\large\boxed{\large\boxed{5.391m/s}}[/tex]
Explanation:
The kinetic energy, KE, of a moving object is given by the formula:
[tex]KE=\dfrac{1}{2}mv^2[/tex]
Where:
- KE is the kinetic energy: 125.6J
- m is the mass of the object (rabbit): 8.642kg
- v is the speed of the object
Solve for v, substitute and compute:
[tex]v=\sqrt{\dfrac{2\times KE}{m}[/tex]
[tex]v=\sqrt{\dfrac{2\times 125.6J}{8.642kg}[/tex]
[tex]v=5.391m/s[/tex]
