The skater must travel at 6 meters per seconds to have a kinetic energy of 360 Joules.
Given the following data:
- Kinetic energy = 360 Joules.
To find how fast (velocity) the skater must travel to have a kinetic energy of 360 Joules;
Kinetic energy is a type of energy that is possessed by an object or body due to motion.
Mathematically, kinetic energy is calculated by using the formula;
[tex]K.E = \frac{1}{2} MV^2\\\\360 = \frac{1}{2} (20)V^2\\\\360 = 10V^2\\\\V^2 = \frac{360}{10} \\\\V^2 = 36\\\\V = \sqrt{36}[/tex]
Velocity, V = 6 meters per seconds.
Therefore, the skater must travel at 6 meters per seconds to have a kinetic energy of 360 Joules.
