Answer:
Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth
Explanation:
Answer:
No
Explanation:
becuse it's not even outer space there's acceleration there's no such thing as Zero acceleration speed except if you're not in motion.
Answer:
18466.68 N
Explanation:
mass of satellite, m = 2210 kg
mass of earth, M = 5.98 x 10^24 kg
distance between surface of earth and the satellite, h = 5.39 x 10^5 m
radius of earth, R = 6.37 x 10^6 m
The force between the earth and the satellite is given by
F = 18466.68 N
b. Newtonian focus
c. Schmidt-Cassegrain focus
d. Schmidt focus
