1) We know that volume= base area x height, so 306.52= 19.4 x height.
To find the height you have to divide 306.52/19.4 which would give you the height. The height is 15.8m.
Answer:
t = 1.94 seconds
Step-by-step explanation:
we have to solve the following polynomial equation:
-16t² + 60 = 0
16t² = 60
t² = 60/16 = 3.75
t = √3.75 = 1.936491673 seconds
the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option
