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
Answer:B
Step-by-step explanation:
2=6
3=9
9=27
You just times the number in box X three times
Area of classroom (rectangular ) = length × width ( also known as breadth )
so....... 12 × 7 = 84 meter squared
