Question

A baseball player is standing at the top of a tower 5 meters high when she throws a baseball out 25 meters. What is the velocity of the baseball that behaves this way? How long is the ball in the air?

a) Velocity = 20 m/s, Time in the air = 2 seconds
b) Velocity = 10 m/s, Time in the air = 5 seconds
c) Velocity = 25 m/s, Time in the air = 2 seconds
d) Velocity = 5 m/s, Time in the air = 5 seconds

Answer 1

The velocity of the baseball is 25 m/s and the time it is in the air is 2 seconds.

Step-by-step explanation:

To determine the velocity of the baseball and the time it is in the air, we can use the equations of motion. Since the baseball is thrown horizontally, the initial vertical velocity is zero. We can use the equation:

Time in the air = 2 * (vertical displacement / acceleration due to gravity)

Given that the baseball is thrown 25 meters horizontally, we can calculate the time it is in the air.

Substituting the values: Time in the air = 2 * (5 / 9.8) = 2.04 seconds

Therefore, the correct answer is:

Velocity = 25 m/s, Time in the air = 2 seconds (c)
