1. A car has tires that have an outer diameter of 31 inches. If the wheels are turning with an angular velocity of 12 rad/s, how far in miles will the car travel in 2 hours? Enter your result rounded to the nearest hundredth

miles

2. A propeller is spinning at a rate of 430 rpm. If the length of one of the blades is 2 feet, what is the linear velocity of a point on the tip of the blade in mph?

mph

3. 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?

One orbit is one revolution around the Sun, or radians. You are being asked to find with units rad/day.

Saturn is approximately 1,427.0 million km from the Sun. How far does Saturn travel in one day?

Use the formula.

What is the speed of Saturn, in km/hr, in its orbit around the Sun?
