I posted this the other day, but I only got one response from someone that was a reminder that the pebble would be following a parabolic path...but what need help with is going about solving the problem....here's the problem and what I tried again..sorry to post the same problem again, but I thought maybe with all the posts no one saw it. Any help would be awesome )(adsbygoogle = window.adsbygoogle || []).push({});

*Romeo is chucking pebbles as gently as he can up to Juliet's window. That is, he wants the pebbles to hit the window with the least possible speed....He is standing at the edge of a rose garden at H = 7.70m below her window and at D = 8.90m from the base of the wall. How fast are the pebbles going when they hit her window?*

Ok, so the horizontal component is 8.9m and the vertical is 7.7m...I tried

- tan= 7.7/8.9 to get theta and then use that to get the hypoteneuse, but i realized, after getting the problem wrong, that I only got the distance of the hypoteneuse, when i really needed the velocity...so how would i find that? thx for any help
