Consider the three inclines shown in the figure. The vertical line is an incline with a 90° angle. (Inclines with 90° angles do exist!) All three inclines are frictionless. Three small identical objects are released from the top of the inclines. What can we tell about their travel times and final speeds?

(Options are: greater than, less than, equal to)

The final speed of C is ... that of B.

The travel time of A is ... that of B.

The final speed of B is ... that of A.

The travel time of C is ... that of B.

The final speed of A is ... that of C.

The travel time of C is ... that of A.

Respuesta :

The final speed of C is equal to that of B.

The travel time of A is less than that of B.

The final speed of B is equal to that of A.

The travel time of C is greater than that of B.

The final speed of A is equal to that of C.

The travel time of C is greater than that of A.

What is speed?

The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.

Consider the three inclines shown in the figure (attached below). The vertical line is an incline with a 90° angle. All three inclines are frictionless. Three small identical objects are released from the top of the inclines.

When the objects are at the same height, they travel with the same height. The travel time is directly proportional to the incline.

Thus, all the statements are completed.
