Question

1. You are driving your car in a circular path on level ground at a constant speed of 20mph .

At the instant you are driving north, and turning left, are you accelerating? If so, toward what point of the compass (N, S, E, W) does your acceleration vector point? If not, why not?

1) A cyclist goes around a level, circular track at constant speed.

Do you agree or disagree with the following statement: "Because the cyclist's speed is constant, her acceleration is zero." Explain.

plz answer both for points

Explanation / Answer

1. Yes, I'm accelerating when I change the direction.. Because since acceleration in a vector quantity, it depends on both the direction and magnitude.. Even if the magnitude is constant and direction is changing, the acceleration is changing. Of I'm driving north and turning left, my acceleration vector is towards south-west..

2. I disagree with the given statement because of the same reason as that of the previous problem.. Here, the cyclist's speed is constant and the direction is changing, so, the accleration is also changing.
