Question

System is shown in the figure. Velocity of sphere A is 9 m/s. Then speed of sphere B will be:

Answer 1

From the above figure, the velocity of the sphere A is 9 m/s. So the speed of the sphere B will be same.

It is because the speed of sphere A will be same to sphere B. Hence, the answer to this question is 9m/s.

When it comes to terminal velocity, it is the maximum velocity attainable by the object.

Answer 2

The speed of the sphere will be 12m/s.
