I have a problem.

Given: T=1.05s
Dx=46.1feet
Angle=15 Degrees.

I need to find Vx and Vy and Vi and Dymax.

Can anyone help me set up the problem? for each thing I need to find...:frown:

you can find Vx using T and Dx, then you can find Vy through trigonometry, and then you'll be able to find the rest.

Put up some work, so we know what to help you with. If you just need a start, you can go with these equations:

Remember that the distance in the x direction is just the component of velocity in the x direction multiplied by the time it takes.
[tex]x=v_{x}t[/tex]

[tex]v_{x}=v_{i}cos(\theta)[/tex]

[tex]v_{y}=v_{i}sin(\theta)[/tex]

Using those, and a basic knowledge of kinematics you should be able to find everything you need.
