Okay, thanks for you're help though. I just have a little trouble understanding things when I can't visualize them on a board, because I'm definitely a person who has to see things to understand them. So, thanks again.
Thanks for your response, but I was told by a friend that I could use this equation...
Delta X= Vi(Cosine Theta)*(2(Vi*Sine Theta)/(Acceleration Y))
He said that I would just simplify this equation and plug in the values that I have given to me. Then he said I would just solve for Vi...
Wayne Brian threw a spear a distance of 201.24 meters. Suppose he threw the spear at a 35.0 degree angle with respect to the horizontal. What was the initial speed of the spear?
Data Known-
Delta X: 201.24 m
Theta (angle): 35.0 degrees
Acceleration (Y): -9.81 meters/seconds/seconds...
