Question

A car is tolling over the top of a hill at constant speed V. At this instant, A N > W

B NC N=W
D We cant tell about n without knowing W

Answer 1

When a car is rolling over the top of a hill, its velocity at the top depends on the net acceleration. Without information about the acceleration, we cannot determine whether the car goes over the top faster or slower than a certain speed.

Step-by-step explanation:

In order to answer the given question, we need to understand the relationship between velocity, acceleration, and speed. When a car is rolling over the top of a hill, it experiences a combination of gravitational acceleration and the acceleration due to the motion.

If the net acceleration is positive, then the car will have a higher speed at the top of the hill (a faster velocity) compared to its speed at the bottom. Conversely, if the net acceleration is negative, the car will have a lower speed at the top of the hill (a slower velocity) compared to its speed at the bottom.

Since the question does not provide information about the acceleration or net acceleration, we cannot determine whether the car goes over the top faster or slower than a certain speed.
