Why can't I understand simple vector questions? I've just started a higher physics and that's what we're learning.(adsbygoogle = window.adsbygoogle || []).push({});

I'm stuck with this question:

A kangaroo was seen to jump to a vertical height of 2.8m. How long was it in the air?

I have the answer at the back of the book, but I don't know how to arrive at the answer! Please help!

Do I need to split it up into the components:

u - initial velocity

v - final velocity

a - acceleration

s - distance

t - time

I know the equations, but when I plug the numbers in, it doesn't come out as the right answer!
