Final answer:
The net force is the horizontal component of the normal force, providing necessary centripetal force, and the acceleration can be found using Newton's second law.
Step-by-step explanation:
The student is asking about the net force and the acceleration of a car on a banked curve where friction is negligible. The net force is the horizontal component of the normal force, providing necessary centripetal force, and the acceleration can be found using Newton's second law.
The resultant force exerted by the car on the road is the normal force, which must have a magnitude equal to the weight of the car when considering only vertical forces.
For the second part of the question, the acceleration of the car, we can solve for it using Newton's second law F=ma, where F is the resultant force, m is mass, and a is acceleration.
