Answer:
190.575 J
Explanation:
Kinetic energy is given by the formula
[tex]KE=0.5mv^{2}[/tex]
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
[tex]KE=0.5\times 35 kg\times 3.3^{2}=190.575J[/tex]
The value of kinetic energy is therefore 190.575 J
