9. A car is traveling at constant speed v across a flat road. First the road curves in a circular arc
radius 2R, and then it curves in a circular arc of radius R. As the car travels from the first curve
the second curve, how is its centripetal acceleration affected?

Answer 1

The centripetal acceleration of the car will increase as it travels from the first curve to the second curve. This is because the radius of the second curve is smaller than the radius of the first curve. Since the centripetal acceleration is directly proportional to the radius of the curve, the car will experience a greater centripetal acceleration on the second curve than it did on the first. The formula for centripetal acceleration is a = v2/r, where v is the velocity of the car and r is the radius of the curve. Therefore, as the radius of the curve decreases, the centripetal acceleration increases.

Answer 2

Uniform Circular Motion:

When a car goes around a circular curve, the velocity of the car definitely changes because of the change in the direction of the car. However, the speed of the car does not necessarily change and circular motion can be sustained by a constant speed. Explanation: i don't know dawg :)
