Question
Time Height
0 sec 380 ft
1 sec 350 ft
2 sec 290 ft
3 sec 200 ft
4 sec 80 ft
The table shows the height of a ball that was dropped from a 380-foot tower. What was the ball's rate of fall during the first 3 seconds?
Responses
A 100 feet per second100 feet per second
B 180 feet per second180 feet per second
C 140 feet per second140 feet per second
D 60 feet per second
C 140 feet per second
To calculate the ball's rate of fall during the first 3 seconds, we need to find the change in height (distance) divided by the change in time.
Change in height = Initial height - Final height
= 380 ft - 200 ft
= 180 ft
Change in time = Final time - Initial time
= 3 sec - 0 sec
= 3 sec
Rate of fall = Change in height / Change in time
= 180 ft / 3 sec
= 60 feet per second
So, the ball's rate of fall during the first 3 seconds is 60 feet per second. Therefore, the correct answer is option D.
