A stone is thrown straight down from a tall building. h=-5t^2-5t+150, h in meters and t in seconds. find the height of the stone 2 seconds after it is throne? the factored form of this equation is 5(t+6)(t-5) if that helps.

Question

tkhunny · Answer

h is the height of the stone.  Simply evaluate h(2).

anonymous · Answer

so i sub H for 2? what about the t in the equation.

tkhunny · Answer

The h-t notation is not very helpful.  Function notation might be more clear.

h(t)=-5t^2-5t+150

Does that make it more clear?  t = 2.
