How do I find the angle then? Do I make another triangle with vx and xy as the legs? I ended with F=357N at 53.7 degrees, is this correct?

I got 7.54 ms. I don't know how to apply force with an angle and time.

To solve it I need to find vi for the y direction. I don't know how to derive the equation: x=vi*t+.5*a(t)^2 to solve for vi.

I think it's as long as it doesn't surpass 2.9m.

The velocity,as it leaves the ramp, is twice what? The calculated velocity of distance/time?

Homework Statement A ball is placed 0.700m from the end of a declining ramp and rolls down the ramp in 0.750s. The marble is also 0.175m from the horizontal. The ball hits a mark on the floor that is 1.70m from the bottom of the ramp on the x-axis. What mount of time is the ball in the air...

projectile and force! :D ! Homework Statement A 3.00 kg projectile must be launched across a room so that it lands 8.50 meters from the launching point. If the ceiling height is 2.90 meters can this be done? If so, what force must be applied over a time period of 0.111 seconds and at what...
