Question

Calculate the kinetic energy of a 115 kg object traveling 3 m/s.

Answer 1

We are asked to determine the kinetic energy of an object given its mass and its velocity. To do that we will use the following formula:

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

Where:

`\begin{gathered} K=\text{ kinetic energy} \\ m=\text{ mass} \\ v=\text{ velocity} \end{gathered}`

Now, we plug in the values:

`K=(1)/(2)(115kg)(3\text{ m/s\rparen}^2`

Now, we solve the operations:

`K=517.5J`

Therefore, the kinetic energy is 517.5 Joules.
