Question

A moterbike of mass 200kg is moving with a velocity 40m/s what is it knitic energy

Answer 1

Answer:

160000 J

Explanation:

We know that

$\bf KE=\dfrac{1}{2} mv^2$

Where

m = mass

v = velocity

$\sf KE = \dfrac{1}{2} \times 200\times (40)^2$

$\sf KE = 100 \times (40)^2$

$\sf KE = 100\times 1600$

$\sf KE = 160000 \; J$
