1. what is the kinetic energy of a ball with a mass of 5 kg rolling
at 10 m/s?

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

if i understood you you wish to calculate power from voltage and current.

we have voltage of 220 volts and current of 5.3 amperes. the power is equal to the product of voltage and current.

where p is power, u is voltage and i is current.

so,

hope this .
