3the components of a 15-meters-per-second
velocity at an angle of 60.° above the horizontal
are
(1) 7.5 m/s vertical and 13 m/s horizontal
(2) 13 m/s vertical and 7.5 m/s horizontal
(3) 6.0 m/s vertical and 9.0 m/s horizontal
(4) 9.0 m/s vertical and 6.0 m/s horizontal

First draw a picture to help make the problem easier. (see attached)

Next you can use sin and cos to find the x and y components of the velocity.

First lets find the vertical component:


Multiply both sides by 15m/s

y ≈ 13 m/s

Now you can find the horizontal component:


Multiply both sides by 15m/s

x = 7.5

Therefore the answer is 2, the vertical (y) component is 13m/s and the horizontal (x) component is 7.5m/s.
