A car is traveling with a constant speed 80 miles per hour a road that makes half a circle. What is the average velocity of the car?
duplicate post. See my answer posted elsewhere
To find the average velocity of the car, we need to calculate the displacement of the car and divide it by the time taken.
The displacement of an object is defined as the change in its position. In this case, the car is moving along a road that makes half a circle. Since the car is traveling at a constant speed, we can assume that it covers the entire distance of the circular road.
The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. Since the car is traveling halfway around the circle, the distance it covers is half the circumference of the circle.
To find the radius of the circle, we need to know more about the road or have additional information given in the question. Without the radius, we cannot calculate the displacement or the average velocity of the car accurately.
