If Kim’s egg traveled a distance of 10m in 5 seconds, calculate the speed. (Speed=distance/time) 2m/s .Use the speed you calculated to determine the acceleration. (Acceleration= speed/time)

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
