I'm having problems with this question. I know it should be simple, but I can't seem to get the right answer.
In this problem, you will use kinematic equations applied to a flea in free fall. Take the magnitude of free-fall acceleration to be g = 9.80 m/s^2.
If a flea can jump straight up to a height of 0.550 m, what is its initial speed v_0 as it leaves the ground?
My answer was 3.28 m/s, which is correct.
How long is the flea in the air?
I don't know which equations to use.
to reach it's max height, I used: t=d/v and got 0.168s
to reach the ground, I used: y1 = -0.5gt^2 and got 0.335s
so the total time I calculate was 0.503s
Can somebody help me?
Thanks
