To form a circle, start from any point A on a plane, or flat surface, and move in a given direction in a straight line until you feel like stopping (point r). Then, turn left or right, and walk until you return to your first stopping point (r), keeping the distance between yourse...
Average speed is the speed of a person over an entire interval of movement. To calculate average speed you use the change in their position divided by the change in time, s = change in d / t, where s is speed, d is distance and t is time....
I then used this number to try and calculate the stopping distance through the equations of straight line motion and then mu through (s = v2/2μg), but kept getting a number of mu around 0.009, which seemed too small to be reasonable. EDIT 1: The car-like object is a "T...
