Vx=cos60(4)
x-component of velocity
<span>If you think about it, it makes a right triangle when you combine all the different types of forces together such as v, vx and vy. Then, you can use trigonometry and soh cah toa in order to figure out vx. </span>
I think it's D cuz D is the heliocentric theory
It would be more than it was but by how much would be 9
For how long? Or is it just speed ??
