Make your child naturally math minded. Book A Free Class. So to pi, times are two pi times 25 by We're getting 2. So this would be your answer for Part II on then. For part B, um, your average speed for half of this If we had, she completes half of the lap and So here she has a circumference length divided by two on ly half a lamp on Lee, only half a lap.
Other my apologies on then here, divided by Now not This will be 20 pie divided by Now the velocity average. However, this is simply displacement. So for average, this average velocity we need to use the displacement. So be displacement over Delta T and the displacement.
And again it makes sense because they make sense that the average velocity is less than the total displayed than the average speed. Because the total distance traveled is greater than the displacement. The diameter is going to be, of course, less than half a semi circle, half a circumference length. And that is the end of the solution.

Averell H. Problem 12 Easy Difficulty A runner covers one lap of a circular track First Name. Your Response. An auto race is held on a circular track. A car completes one lap in a time of How fast is the distance between the friends changing when.
A runner completes one full lap around a meter track. What is her displacement? A runner circles a track of radius 50 m in 50 s moving at a constant rate. If the runner was initially moving north, what has been the runner's average acceleration when halfway around the track?
