5)Suppose a 6.0×1010 kg meteorite struck the Earth at the equator with a speed 2.5×104 m/s, as shown in (Figure 1) and remained stuck. Part A By what factor would this affect the rotational frequency of the Earth (1rev/day)? Express your answer using two significant figures. Δω/ω=?

A uniform solid disk with radius 8 cm has mass 0.5 kg (moment of inertia I = (1/2)MR²). A constant force 14 N is applied as shown. At the instant shown, the amount of string that has wound off the disk is d = 22 cm, and the angular velocity of the disk is 45 radians/s into the page. d F

4. The sun has a rotation period (about an axis through its center) of about 25 days, rather than the one day for our earth. In about 5 billion years, the sun will become a red giant star and its radius will expand to about the orbit of the earth. Determine the new rotational period of the sun once it becomes a red giant. Hint: If your system is the sun, then there are no external torques acting on the system during this process. Also, assume the sun (and the red giant) to be solid spheres.

Neptune has a mass of 1.01026kg and is 4.5109km from the Sun with an orbital period of 165 years. Planetesimals in the outer primordial solar system 4.5 billion years ago coalesced into Neptune over hundreds of millions of years. If the primordial disk that evolved into our present day solar system had a radius of 1011km and if the matter that made up these planetesimals that later became Neptune was spread out evenly on the edges of it, what was the orbital period of the outer edges of the primordial disk?

Suppose you are standing within the rim of a circular space station, in outer space. The rim revolves around the center of the space station at a speed of 300 (m/s). If the radius of the station is 3,000 (m). 1) Draw and label a diagram for this case. 2) What is the rotational speed of the space station? 3) From the equation a = V^2/r (a = simulated gravity/acceleration), calculat the acceleration (a) at the rim. 4) From the equation Fc = [m (V^2)] / r , calculate centripetal force Fc assuming the mass of the station is 5,000 (Kg).
