Question

Calculate the kinetic energy of a roller coaster that has a mass of 1,778.6 kg and is traveling with a velocity to 24.5 m/s at the bottom of the first hill.

Answer 1

Given:

The mass of the roller coaster is m = 1778.6 kg

The velocity of the roller coaster is v = 24.5 m/s

To find the kinetic energy of the roller coaster.

Step-by-step explanation:

The formula to calculate the kinetic energy is

`K\mathrm{}E\text{. =}(1)/(2)mv^2`

Substituting the values, the kinetic energy will be

`\begin{gathered} K\mathrm{}E\text{. =}(1)/(2)*1778.6*(24.5)^2 \\ =533802.325\text{ J} \end{gathered}`

Final Answer: The kinetic energy of the roller coaster is 533802.325 J.
