A car races at a constant speed of 25 m/s around a circular track with a radius of 150 meters. Consider 1/4 of a lap starting on the south side (heading east) and ending on the east side (heading north).
A. how much time does the car take to travel between the two points?
B. what is the displacement between the starting and ending points?
C. what is the average velocity? D. What is the change in velocity? What is the average (vector) acceleration? PLEASE SHOW ME HOW YOU DO IT, NOT JUST ANSWERS!
At t = 5.0 seconds, the cheetah is standing still, having knocked over the gazelle. Illustrate what is the average acceleration of the cheetah from t = 0 to t = 5.0 seconds?
why does d account for the reduction of the distance from 8.5 km to a 0 distance. Is this not a reflection of displacement rather than just distance
