Part B = 0.0748 rev

Part C = 1.02 m/s

Part D = 3.59 m/s^2

Compute the angular velocity of the fan after time 0.201 s has passed.

Through how many revolutions has the blade turned in the time interval 0.201 s from Part A?

What is the tangential speed v_{tan}(t) of a point on the tip of the blade at time = 0.201 s?

What is the magnitude α of the resultant acceleration of a point on the tip of the blade at time t = 0.201 s?

Part A = 4.26 * 10^37 kg

Part B = 2.14 * 10^7

Part C = no

Part D = 6.31 * 10^10 m

Part E = yes

Determine the mass of the massive object at the center of the Milky Way galaxy.

Express your answer in solar masses instead of kilograms, where one solar mass is equal to the mass of the sun, which is 1.99 * 10^30 kg.

Observations of stars, as well as theories of the structure of stars, suggest that it is impossible for a single star to have a mass of more than about 50 solar masses. Can this massive object be a single, ordinary star?

Many astronomers believe that the massive object at the center of the Milky Way galaxy is a black hole. If so, what is its Schwarzschild radius R_{s}?

Would a black hole of this size fit inside the earth’s orbit around the sun? The mean distance from the sun to the earth is 1.5 * 10^11 m.

Part A = At a distance greater than r

Part B = Tm is greater than Te

At what distance from the center of the earth does the second satellite orbit?

ow does the time T_{m} it takes the satellite circling the moon to make one revolution compare to the time T_{e} it takes the satellite orbiting the earth to make one revolution?
