In the diagram at the right, draw vector arrows (straight lines with arrowheads) which indicate the following for an object which is moving in a clockwise circle. the net force at point A. the acceleration at point B. the velocity at point C.

A car is traveling a road that makes quarter of a circle with a constant speed s. What is the magnitude of the average velocity v of the car?

Which of the following statements are true. Select all correct answers a. The direction of centripetal acceleration is pointing towards the tangent direction of the circular trajectory b. The direction of centripetal acceleration is pointing towards the center of the circular trajectory c. The tangential velocity is always constant in a circular motion. d. The angular velocity is always constant in a circular motion.

Suppose that a bus is traveling at 50 mi/h cast along Main Street- and that you're on the bus running to the front of the bus at 10 mi/h. What is your velocity relative to Main Street? That's easy...60 mi/h east. Vectors are not necessary to solve this problem. However, if you can understand how vectors work in simple situations as shown below, then you can understand how they work in more complex situations. = 50 mi /h east v,-10 mi/h east Vector Representation R=+v = 60 mi /h east Arrows are used to depict each vector. R represents the resultant of adding the vectors in question. R is also a vector. Q2 How is the magnitude of each vector depicted graphically? Q3 How is the direction of each vector indicated?

A racing car is moving around the circular track of radius 500 meters shown above. At the instant when the car's velocity is directed due east, its acceleration is directed due north and has a magnitude of 2 meters per second squared. When viewed from above, the car is moving A. clockwise at 32 m/s B. counterclockwise at 16 m/s C. counterclockwise at 32 m/s D. clockwise at 16 m/s
