1) cos 60o = vx0 / 50 => vx0 = 50.cos 60o = ?
2) sin 60o = vy0 / 50 => vy0 = 50.sin 60o = ? OK so I use my calculator for 1) and I insert in my calculator cos 50x60 = 42.42 but this is not the right answer because the answer is 25 m/s because the answers are in the back of my book.
FOr question number 2) I not 100 % sure but I do the same thing sin 50x60 = 42.42 in this case I get the same answer than in cos, and the answer is 43 m/s so I don't know about this because I got 42.42 so maybe this is right.
