Physics easy 10 points ?

vx = V cos22, vy = V sin22, 10m = vx t, t = 2vy/ g.
Hence,
10m = 2 vx vy /g = 2 V^2 cos(22) sin(22) / g =>
V^2 = (10 m)sin(44) * g = 68.08 m/s.
And that's the answer to #1.

Then, #2, vx = 68.08 m/s * cos(22 deg) = 63.12 m/s

10. You Can Get Out of a Black Hole
This is actually a joke; there is no way to get out of a black hole (that’s why they're black!) But the APS outreach website PhysicsCentral has an article about this fascinating subject.

1. Physics Will Help You Get into College, Get a Job, and Find Love
Physics makes you more attractive to university recruiters, future employers, and that cutie you have your eye on. (You'll just have to trust us on that last one).

1. Use the range equation: x = V²sin(2Θ) / g
10.0 m = V² * sin44.0º / 9.8m/s²
V = 11.9 m/s

2. Vx = VcosΘ = 11.9m/s * cos22.0º = 11.0 m/s

Hope this helps!
