Question

question 3
a racecar is moving counterclockwise on a circular path as shown in the diagram. at this instant, the car is at point p and moving at a speed of 100 mph. in what direction does the centripetal acceleration vector point?

Explanation:

Step1: Recall centripetal - acceleration property

Centripetal acceleration always points towards the center of the circular path.

Answer:

The centripetal - acceleration vector points towards the center of the circular path. So, if we assume the center of the circle is below point P (depending on typical circular - motion diagrams), the direction is $\downarrow$.
