The answer is 52.79 m.
I used this formula to get the formula for Vy:
v^2=vi^2+2(a)(x)
And got
Vy=square root (19.6 h)
Then I used that and put it in this formula:
tan(65) =Vy/Vx
tan(65) = square root (19.6 h)/15.0
Then I rearranged it to:
h=[(15.0)(tan65)]/19.6
h=52.79 m
draw a horizontal straight line from 25 to 75 and connects the line drawn at 75 to the bottom of the graph (0) at 90 with a straight line
Answer:
a. A
Explanation:
Kepler's First Law says that the orbits of planets are ellipses with the sun at one focus of the ellipse. Moreover, Kepler’s Second Law says that the line joining the planet to the sun sweeps out equal areas in equal times as it moves along its orbit. Finally, Kepler’s Third Law says that the ratio of the squares of the periods for two planets is equal to the ratio of the cubes of their semi-major axes.
By these laws, the comet A will have lower orbital speed.
