The answer is 16. I’ve done this before and i got a 100% on it! Good Luck!!
For this case we have an equation of the form:
h (t) = - (1/2) * a * t ^ 2 + vo * t + h0
Where,
vo: initial speed
a: acceleration:
h0: initial height.
We have the following equation:
h (t) = - 16t2 + 19t + 110
Therefore, the initial velocity is:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown:
vo = 19 feet / s
$22 - $4 (for the movie) = $18.
$18 / $6 (per game) = 3 games
