I thought that the vertical velocity at maximum height would be zero, though...
Anyway, I tried using v*sin theta as the v at KEf and I got the wrong answer:
PEi + KEi = PEf + KEf
(3.18kg * 37 m * 9.8m/s^2) + (1/2 * 3.18kg * (41.6m/s)^2) = (9.8m/s^2 * 3.18kg)height + (1/2 * 3.18kg *...
I've been working on this problem for almost TWO HOURS ( ) and I still don't understand it. Please help!
We're in the Work, Power and Energy unit right now and I have to solve this problem:
A 3.18-kg ball is launched from a cliff at 60 degrees from the horizontal. Determine the maximum...
