Question

Carlo, having a mass of 50kg, running to the next classroom for his next subject. If his running speed is 10m/s, what is his kinetic energy?

Answer 1

Kinetic energy = 2500 J

Explanation:

To calculate the kinetic energy of an object, we can use the following formula:

`\boxed{E_k = (1)/(2)mv^2}`,

where:

`E_k` = kinetic energy

m = mass of the object

v = speed of the object

In this question, we are told that Carlo's mass is 50 kg and his speed is 10 m/s. Using this information and the formula above, we can calculate Carlo's kinetic energy:

`E_k = (1)/(2) * 50 * (10)^2`

`= (1)/(2) * 50 * 100`

`= \bf 2500 \: J`

Therefore, Carlo's kinetic energy is 2500 J.
