To determine the height of a flagpole, Abby throws a ball straight up and times it. She sees that the ball goes by the top of the pole after 0.537 s and then reaches the top of the pole again after a total elapsed time of 4.57 s. How high is the pole above the point where the ball was launched? CHOOSE ONE: 13 m 12 m 26 m 10 m 16 m

Expert Solution

Step 1

Given :

Time taken to reach the pole from initial position (A to B), t₁= 0.537 s

Time taken to reach the pole from maximum height (C to B'), t₂= 4.57 s

Determine the height of the flagpole from the point where the ball was launched.

Let h be the height of the flagpole and h₁be the height travelled by the ball above the pole(i.e., from B to C to B').
