What do I have wrong in here?
A stone is thrown vertically upward at a speed of 60.0m/s.
a) How long after being thrown is it 175m above ground?
So i did -
d = V1t + 1/2at^2
175 = 60t + 1/2 (10)t^2 (rearranged and divided it all by 5)
0 = t^2 + 12t - 35
And I can't get the factors.
We were asked to consider acceleration as 10.0m/s^2
