Question

An athlete starts at point and runs at a constant speed of 6.60 m/s around a round track 200m in diameter, as shown in the figure below

Additionall information for points A-B

Runner's x,y avg velocity for points 4.20

x component of avg acceleration .277

y componenent -.277

I thought I would just double it but obviously thats not right.

Explanation / Answer

a) Horizontal distance = 200m

Circular distance = d/2 = 314m

Time = 314/6.6 = 47.58s

vx = 200/47.58 = 4.20 m/s

b) Displacement in the y direction = 0

vy = 0

c) ax = 0.277. Same as between A & B

d) ay = 0
