Question

Which of the following physical quantities remained constant while the baseball was in the air after being thrown at a 30° angle with respect to the ground and reaching the ground in 2 seconds?

A) Vertical component of velocity
B) Horizontal component of velocity
C) Total mechanical energy
D) Air resistance

Answer 1

The horizontal component of velocity remains constant while the baseball is in the air.

In this scenario, the horizontal component of velocity remains constant while the baseball is in the air. This is because there are no additional horizontal forces acting on the ball after it is thrown. As a result, the ball continues to move horizontally with the same velocity throughout its flight.
