1. Assume that Earth's orbit around the sun is circular, and that the radius of
Earth's orbit is about 1.50 x 10" km. Earth completes a full revolution around the
sun in 365 days.
a. Calculate the tangential velocity of Earth in km/s (you have to convert days
to seconds first).
b. Calculate the acceleration of Earth towards the sun in m/s (you have to
convert days to seconds and km to m first).
2. A certain Ferris wheel with radius 14.0 m is turning at speeds of 7.00 m/s at its
farthest point.
a. What is the acceleration experienced by a car attached to the rim of the
Ferris wheel?
b. How long does it take for the Ferris wheel to complete one full revolution?
Currently, the moon goes around the earth once every 27.3 days. If the moon could be brought into a new circular orbit with a smaller radius, its orbital period would beA. More than 27.3 days.B. 27.3 days.C. Less than 27.3 days.
