In circular motion we know that there is two type of acceleration that Cheryl experience
1. Tangential acceleration
2. Centripetal acceleration
here given that
for centripetal acceleration we know that
now we know that both centripetal acceleration and tangential acceleration is perpendicular to each other
so total acceleration is vector sum of both and given as
so total acceleration is 8.54 m/s^2
force= mass x acceleration= 0.2 x 20= 4 N
(N stands for newton btw)
Answer: The answer is C, Yes, her star will have appeared to move very slightly to the west.
Explanation: If your looking at a certain star, it usually goes to the west at night time very slightly, it doesn't go to the east because the Earth's axis tilts mostly on the west side. So it makes it true.
Answer:
B hopefully this helps you with work
