Question

A 35 Kg child has the speed of 3.3 m/s after sledding down a hill. What is the child's KINETIC

ENERGY?

Answer 1

190.575 J

Step-by-step explanation:

Kinetic energy is given by the formula

`KE=0.5mv^(2)`

Where KE is kinetic energy, m is the mass of the child in Kg and v is the speed.

Kinetic energy can be transformed to other forms such as potential energy.

Given that the child has a mass of 35 kg and its speed is 3.3 m/s then we substitute these for m and v respectively.

Therefore, kinetic energy will be

`KE=0.5* 35 kg* 3.3^(2)=190.575J`

The value of kinetic energy is therefore 190.575 J
