A marble with a horizontal velocity of 8 m/s is rolled off of a 10 m high table. What is the final horizontal velocity right before it hits the ground?

Respuesta :

Answer:

Assuming there is no air resistance, 8 m/s.

Explanation:

Since the only force acting on the marble before and after falling is gravity, and gravity only acts in the negative y direction, the horizontal velocity does not change. To calculate with air resistance and frictional force of the table, you would need more information.
