Question

Suppose a 2.0kg bird is flying at a speed of of 1m/s. It’s kinetic energy would be what?

Answer 1

As we know that the formula of kinetic energy will be

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

now here we know that

m = 2 kg

v = 1 m/s

so from the above equation we have

$KE = \frac{1}{2}(2)(1^2)$

$KE = 1 J$
