Question

Please help Last question!!!!! Ill give medal and fan you!!!!!!!!!


The function H(t)=-16t^2+vt+s shows the height H(t), in feet, of projectile launched vertically from s feet above the ground after t seconds. The initial speed is v feet per second.

Part A: The projectile was launched from a height of 82 feet with an initial velocity of 60 feet per second. Create an equation to find the time taken by the projectile to fall on the ground.

Part B: What is the maximum height that the projectile will reach?

(Part C and D will be in comments

Answer 1

Part C: Another object moves in the air along the path of g(t)=10+63.8t where g(t) is the height, in feet, of the object from the ground at time t seconds.

Use a table to find the approximate solution to the equation H(t)=g(t) and explain what the solution represents in the context of the problem. [Use the function H(t) obtained in Part A and estimate using integer values]

Part D: Do H(t) and g(t) interest when the projectile is going up or down, and how do you know?

Answer 2

For part a.
First, replace the variables in the equation with the values you are give.
Can you do that and show it?

Answer 3

actually that's one of my problems I forget how to use the formula
