The Attempt at a Solution
Hey, I did part a and b. Although I need a little help with part c.
I know you're supposed to solve for t^2 but I don't know what value to use for acceleration.
I'd use the quadratic formula to solve for t^2, but I'm just not sure which values to use...
At first I thought the initial velocity would be zero and the acceleration would be zero but then that left me with:
-1/2 * (4.8 m/s^2) = 0 which doesn't lead to the right answer. Could you guys point me in the right direction?
