    Linear, and angular velocity

    For each of the following, enter your answers using scientific notation with 4 significant figures. For example, 1,234,000 would be written as 1.234e6. Use the value of 1 Earth year = 365.26 days, if needed for your conversions.



    Saturn orbits the Sun once every 29.456 Earth years. Assuming the orbit of Saturn is circular,Through what angle (in radians) does a line from the center of the Saturn to the center of the Sun sweep in one day?

    I found that the angle swept out in one day is 5.84010-4 rad
    Saturn is approximately 1,427.0 million km from the Sun. How far does Saturn travel in one day?

    I found that Saturn travels 8.334105 km in one dayWhat is the speed of Saturn, in km/hr, in its orbit around the Sun?

    - Here's where I'm stuck, I beleive that this is going to be the linear velocity in the fomula v=rw
    r=
    1,427.0 million km or 1427000000 or 1.427x10^9

    1,427.0 million km
    $1,427.0 \text{ million km } = 1,427 \times 10^6 \text{ km }= 1.427 \times 10^9 \text{ km}$

    You have already found its velocity in Km/day (the answer you gave to the second question) - simply convert to km/hr.
