So are you saying that for Part C, the acceleration is simply (-10m/s2) since that is the force of gravity pushing down on the ball?

Regarding the vectors: Is it enough then to write the answer for the distance question as "The ball has traveled 125 metres upward by the time it stopped rising" --- or am I missing something?

Here is my work. (Remember that in the question it says, force of gravity may be rounded to 10m/s) DISTANCE: 1/2mv2 = mgh [Mass cancels itself out] 1/2v2 = gh -------------------------------------------------- 1/2(502) = 10h 1/2(2500) = 10h 1250 = 10h 1250/10 =...

Meaning of: "Indicate magnitude & direction of all vectors" I don't actually need help solving this problem I am working on, as I already have the answers. What I need help with is understanding this phrase: "Include both magnitude & direction of all vectors" --- What does this mean? Here is...

If anyone else could offer one last bit of advice: Is there a formula that I can use to find (t) before finding (h), if all that is known is the initial velocity?

127.5/50=t t=2.55 The last question is "What is the ball's acceleration during this time?" - What should I do to figure that out? Also, is there a way to figure out (t) before figuring out (d)? I ask because that question that asks for (t) comes first...

1250=gh 1250=(9.8)(h) 1250/9.8=h h=127.5m Is that correct? If so, how then would I get the time to reach maximum height?

I don't think mass needs to be accounted for, for this question. The question assumes there is no air resistance, and I guess the only relevant factors in figuring out the answers are initial velocity and gravity. For the first formula I get: 1/2(50)^2 = 1250 J So, what can I do with that...

0 m/s --- So what would I do with that number? (If I should know by now, again I must apologize as I haven't used anything but basic math in years)

Right, that is given in the question. I'm not sure what to do with that...

Hello everyone. I'm sorry for asking such basic questions without offering much in a solution attempt, but the problem is - I have no idea how to answer them! I'm obviously a non-scientist and my math skills aren't so great either. But I would like if someone could simply show me HOW to answer...
