Yes, the 3 feet are important.
<span>You can consider the datum (y=0) at 3' from the ground, and the ground is therefore at -3 feet. </span>
<span>The vertical initial velocity, vy, is u*sin(θ), so it gives </span>
<span>vy=55sin(44°)=38.21 approx. </span>
<span>The (vertical) distance travelled is given by: </span>
<span>S=vy*t-(1/2)gt² </span>
<span>where </span>
<span>S=-3 (ground) </span>
<span>vy=55sin(44°), and </span>
<span>g=32.2 ft/s² </span>
<span>Solve for t. </span>
<span>I get -0.08 and 2.45 s.</span>
Answer:
C)
Step-by-step explanation:
Constant means there is no variable attached to the number.
Coefficient means there is a variable attached to the number.
Answer:
x = 4
Step-by-step explanation:
An undefined slope means the line is vertical.
The equation for vertical lines is "x = a number"
Since the x coordinate in this question is 4, the equation of the vertical line passing through the point (4,3) and (4, 3) would be --> x = 4
<u><em>x = 4 is the answer</em></u>
