Homework Statement
The driver of a boat sets the throttle and ties the wheel, making the boat travel at a uniform speed of 12.5m/s in a circle with a diameter of 115m. Through what angular distance does the boat move in 4.00 minutes? What arc distance (in meters) does it travel in this time?
Homework Equations
The Attempt at a Solution
The diameter is 115m, radius is 57.5m, time is 4 min.
But noww is the average velocity 12.5m/s or is 12.5m/s final speed? I know that it is going at constant speed and it does have acceleration. So we take 12.5m/s x 240sec = 3,000m But for the arc distance you take the radius of 57.5 x 2pi(57.5) = 20,763m?
