Question

Calculate the kinetic energy of an 84-kg scooter moving at 18 m/s .

Answer 1

using ½mv²
= ½×84×18×18 = 13608joules

Answer 2

13608 joules

Step-by-step explanation:

We are given that mass of scooter=84 kg

Speed of scooter=18 m/s

We have to calculate the kinetic energy

We know that formula of kinetic energy

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

Substitute the values then we get

K.E=
`(1)/(2)* 84* (18)^2=13608 joules`

Hence, the kinetic energy of an scooter=13608 joules
