Convert 1.7miles to feet
1mile = 5280 feet
1.7 miles x 5280 feet/1mile = 8976 feet
Elevation = 520 feet
Make a right triangle and mark the hypotenuse as the distance traveled and Line B as the elevation.
Distance = A
Elevation = B
You'll get:
sin <a = A / B
sin <a =520 / 8976
= inverse sine(sine^-1) 0.057
=3.321
hope this helps :)
"decreasing the distance of the space shuttle from Earth"
F = Gm(1)m(2)/R²
where R is the distance between the 2 objects, as it decreases, the force increases.
15x 9.8 x .3 = 44.1
15 x 9.8 x 1 = 147
147 - 44.1 = 102.9J
102.9 J
