Given :
Magnitude of vector, v = 15.3 m
Angle of vector from horizon, 
.
To Find :
The x - component of the given vector.
Solution :
We know, a vector is given by :
Now, the x - component is :
Hence, this is the required solution.
No, the light from the overhead would show you only the coin outline.
To get this we need to know how long he was traveling. To know that we need to solve for the time it took for him to hit the ground. This is given by the vertical height he started at and the equation of motion for falling objects. The position function is
Y= -(9.8/2)t^2 + 50 = 0
t=3.19s
That's how long he's in the air. When he hits the ground he stops moving forward so this is also the amount of time he was moving at 100m/s horizontally. Now use speed distance relationship
X=vt
And solve for v
100m/3.19s = 31.35m/s
C. the order from closest to the sun to furthest is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune so C. would be the opposite heading towards the sun. A good mnemonic to use is MVEMJSUN: My Very Educated Mother Just Served Us Nectarines
