Select the true statement regarding accelerations of the cars.

Answer to Problem 1FC
Option C, “Car A is not accelerating, but Car B is accelerating” is true.
Explanation of Solution
Description:
When the car is travelling through a straight path with a constant speed, the car remains in equilibrium. The magnitude and direction of acceleration are zero at equilibrium. Car A is travelling through a straight path and hence it is not accelerating.
While the car travels through a curved path or a turn, the motion of car turns in a circular motion. Hence, the centripetal acceleration exists since it is not in equilibrium. Therefore, the acceleration is present while moving through the curve. Car B is travelling in a curved path and hence car B is accelerating.
Conclusion:
Thus, option C., “Car A is not accelerating, but car B is accelerating” is true.

- An object is placed 24.1 cm to the left of a diverging lens (f = -6.51 cm). A concave mirror (f= 14.8 cm) is placed 30.2 cm to the right of the lens to form an image of the first image formed by the lens. Find the final image distance, measured relative to the mirror. (b) Is the final image real or virtual? (c) Is the final image upright or inverted with respect to the original object?arrow_forwardConcept Simulation 26.4 provides the option of exploring the ray diagram that applies to this problem.
