Thank you everyone for your help. I know it's a simple problem. My instructor only gave me 2 points out of 20 for the answer, and I'm fairly certain that isn't reasonable. I've suspected that he was incompetent, but that's a different matter. I decided it would be best to take the course at a...

x = 0m/s + (10m/s * 1.0 s) + (-9.80m/s2 * 1.0s^2)/2 = 5.1 m Ok, is this right?

We were instructed to round after each section of the problem. In b I used the formula x = x0 + 1/2(v0 + v)t. x0 is x naught and so on.

Please tell me if I have done this correctly. A ball is thrown upward from the ground with an initial velocity of 10 m/s. Assume all digits are significant. a. How long before the ball reaches its maximum height? t = (0m/s - 10m/s) / -9.80m/s2 t = 1.0s b. What is the ball's maximum...
