Question

A polar beer runs at a speed of 11m/s With 23,000 J of kinetic energy. What is a polar bear mass?

Answer 1

Mass of the polar beer is 380.2 kg

Step-by-step explanation:

As we know that kinetic energy is given as

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

now we know that

`K = 23000 J`

also we know that the speed of the beer is 11 m/s

now we have

`23000 = (1)/(2)m(11^2)`

`m = 380.2 kg`
