A second basemen tosses the ball to the first basemen, who catches it at the same level from which it was thrown. The throw is made with an initial speed of 19.0 m/s at an angle of 34.5 degrees above the horizontal.

what is the horizontal component of the balls velocity just before it is caught?
how long is the ball in the air?

Explanation:

Given

Initial speed of ball

Launch angle

As there is no acceleration in horizontal direction therefore there is no change in velocity

thus horizontal velocity remains unchanged

Time of flight of projectile is

Thus time for which it is in air is 2.12 s

as indicated in the question radial contains rad, also found in radius, so the fracture's would span the radius.
