The initial approach to measuring individual differences in sensation was the use of absolute thresholds. In the 21st century, researchers use a more sophisticated approach that takes an observer's response bias into account. This approach is termed theory.

Signal Detection Theory

Explanation:

According to this theory, there are a number of factors that determine how a system will detect a signal and the point at which the threshold level will be pinpointed. E.g. in humans factors such as fatigue, experience, expectations can affect the applied threshold.

we can solve this via the kinematic equation:

where the vertical velocity is zero and so:

since the height of the building is 29.3 meters then:

the ball was in motion for approximately 2.45 seconds

all you have to do is look at the pictures to find hope this is the lesson you were also hope this .
