Homework Statement
A projectile is launched with a horizontal velocity of 10 m/s and a vertical velocity of 20 m/s. What is the magnitude and direction of the projectile’s initial velocity?
The Attempt at a Solution
I've tried using the trigonometric method but I end up with only 1 side and 1 angle which isn't good. I could logically think that since one side is 20 and one side is 10, the angle would be90 / 3 = 30
30 * 2 = 60
But the answer sheet says 63 degrees. :"(
I found the magnitude but the problem is I can't find the direction. More specifically, at what degree is it traveling at.
The magnitude is 22.
So it should be
22 m/s [Up x Horizontal]
x = an unknown angle
I'm having trouble finding the value of x.
Than you. :3
NVM GOT IT. LOL :D
