Question

How do you solve this?​

Answer 1

Horizontal component = 9.6

Explanation:

Recall that the horizontal component is given by the cosine projection;

`v_x=|v_0| * cos(\theta)`

which in our case (using the fact that in each degree of angle one has 60 minutes of angle, and therefore 30 minutes of angles is the same as 0.5 degrees) becomes:

`v_x=12.6 * cos(40.5^o)=9.5811`

And rounding to the nearest tenth as requested, we have:

`v_x=9.6`
