Question

A child throws a baseball straight up into the air and it takes 4.5 seconds to reach maximum height. What is the total time of flight for the baseball after being thrown and the baseball player catching it? What are the known and unknown variables? And what equation must be used?

Answer 1

Answer:

9 s.

Explanation:

The following data were obtained from the question:

Time (t) taken to reach the maximum height = 4.5 s

Time of flight (T) =?

The time of flight (T) is simply defined as the total time spent by the ball in the air. Mathematically, it defined as twice the time taken (t) to reach the maximum height i.e

T = 2t

With the above formula, we can obtain the time of flight as follow:

Time (t) taken to reach the maximum height = 4.5 s

Time of flight (T) =?

T = 2t

T = 2 × 4.5

T = 9 s

Thus, the time of flight of the ball is 9 s.
