Hey there. I've got a physics problem that is troubling me. I feel like I should be able to do it, but i's been a while since I've done much physics and I could use some help.
Mike jumps off a springy diving board located 10.0m above the surface of a swimming pool on the moon. He launches straight up at 15.0 m/s. (assume he misses the diving board on the way back down.) If gmoon is exactly one-sixth gearth, at what time does he hit the water?
I used, x=x0+v0t+1/2at2, but my answers didn't work when I plugged them back in, I think my math may be way off or something.
0=10+(15)t+(1/2)(-9.80/6)t2
0=10+15t-(9.80/12)t2
-10=t(15-(9.80/12)t)
t= -10, 30.61
It can't be -10, but when I plug both of them back into the original equation, it never works out.
Thanks in advance for any help!

The Attempt at a Solution
0=10+(15)t+(1/2)(-9.80/6)t2
0=10+15t-(9.80/12)t2
-10=t(15-(9.80/12)t)
t= -10, 30.61
