Answer:
after 11.07secs
Step-by-step explanation:
Given the height of an object modeled by the equation
H = 16T² - 1960
The height of the object on the surface of water is zero, hence H = 0
Substitute
0 =16T² - 1960
Swap
16T² - 1960 = 0
16T² = 1960
T² = 1960/16
T² = 122.5
T = 11.07
Hence the rock will hit the surface of the water after 11.07secs

Answer:
I'm just trying to make this as simple as possible for you.
The value of m is 5.
How?
We must follow a few simple methods to solve this problem.
Well, four to be precise.
All we need to do is add 4 to both sides of the equation, or 
Then, we simply by adding the numbers together to get -5m = 36 + 4, or, 40.
Following that, we divide both sides of the equation by the same term, giving us the equation −
