Hi

Break down the following velocity vectors into their x-component and y-component: (Make sure your calculator is in degrees)

1) v_{0} = 25 m/s at an angle of 37 degrees above the horizontal

2) v_{0} = 32 m/s at an angle of 63 degrees above the horizontal

When we resolve a vector

The horizontal A Cos theta and vertical component is A Sin theta ( Where A is a vector to be considered)

So Case1

Horizontal = 25 Cos 37 ( as V0 Cos theta)

and vertical = 25 Sin 37

Similarly for case 2

Horizontal = 32 Cos 63

and Vertical 32 Sin 63

Now plug in the values of Cos 37, Sin 37 , Cos 63 and Sin63 ( All Angles are in degrees)
