Question

Calculate the kinetic energy of scooter that has a mass of 45 kg and a velocity of 15 m/s.

Answer 1

Given:

The mass of the scooter, m=45 kg

The velocity of the scooter, v=15 m/s

To find:

The kinetic energy of the scooter.

Step-by-step explanation:

The kinetic energy of an object is the energy possessed by it due to its motion. The kinetic energy of an object is directly proportional to the square of the velocity of the object.

Thus the kinetic energy of the scooter is given by,

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

On substituting the known values,

`\begin{gathered} E+(1)/(2)*45*15^2 \\ =5062.5\text{ J} \end{gathered}`

Final answer:

The kinetic energy of the scooter is 5062.5 J
