Best ResponseYou've already chosen the best response.0The function H(t) = 16t2 + vt + s shows the height H (t), in feet, of a projectile launched vertically from s feet above the ground after t seconds. The initial speed of the projectile is v feet per second. Part A: The projectile was launched from a height of 100 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. (2 points) Part B: What is the maximum height that the projectile will reach? Show your work. (2 points) Part C: Another object moves in the air along the path of g(t) = 20 + 38.7t 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] (4 points) Part D: Do H(t) and g(t) intersect when the projectile is going up or down, and how do you know? (2 points)

Best ResponseYou've already chosen the best response.0Hmm. It is not correct. dw:1432914354831:dw The given equation represents the parabola openning downwards. Also it says that that will be the path folowed by the projectile if you take coordinate axis in a usual way. So imagine it being the actual trajectory of your particle. The parabola will cut taxis in two points. One of them is the moment when it hits the ground, right?

Best ResponseYou've already chosen the best response.0what can you say about the value of H(t) when the projectile hits the ground?

anonymous

Best ResponseYou've already chosen the best response.0first answer about hte value of H(t) at the moment when it is on the ground

Best ResponseYou've already chosen the best response.0remmember that it represents the hight. How much high is something from the ground if it is on the ground?

Best ResponseYou've already chosen the best response.0so your equation becomes: 0=16t^2+vt+s Now lets use next information given. It says it was trown from 100 feet hight How we can introduce this informatyion in our equation?

Best ResponseYou've already chosen the best response.0what does s represent?

anonymous

Best ResponseYou've already chosen the best response.0Actualy it represents initial hight. So substitute s=100

Best ResponseYou've already chosen the best response.0and v=60 and you got the equation for t when it hits the ground

anonymous

Best ResponseYou've already chosen the best response.0ok well thank you you helped me understand it more now
