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

Answer:

Mass of the polar beer is 380.2 kg

Explanation:

As we know that kinetic energy is given as

$K = \frac{1}{2}mv^2$

now we know that

$K = 23000 J$

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

now we have

$23000 = \frac{1}{2}m(11^2)$

$m = 380.2 kg$
