Question

What is the kinetic energy of a car that is traveling at 14.1 m/s if it has a mass of 1487 kg? Submit your answer in exponential form.

Answer 1

1.48 x 10^5 K

Explanation:

Given:

Velocity (v) = 14.1 m/s

Mass (m) = 1487 kg

The kinetic energy is calculated using the following formula:

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

We substitute and determine the value of the energy

`\begin{gathered} E=(1)/(2)\cdot1487\cdot\left(14.1\right)^2 \\ \\ E=147815.235=1.48\cdot10^5\text{ J} \end{gathered}`

The kinetic energy is equal to 1.48 x 10^5 joules.
