HELP! THIS IS ALGEBRA 1 HW!
A rocket is launched from atop a 101 foot cliff with an initial velocity of 116 ft/s.

a) Substitute the values into the vertical motion formula h= -16t^2 + vt + h ( with a bottom exponent of 0). Let h(t) = 0

b) Use the quadratic formula to find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second.

anonymous · Answer

start with 
$$h(t)=-16t^2+116t+101$$

anonymous · Answer

btw $v_0$ and $h_0$ are called "v zero" and "h zero" respectively

How did you get 101 there? It was $$h _{0}$$

mopsy510 · Answer

Ohh

anonymous · Answer

in your case $v_0=116$ and $h_0=101$ they are the initial values, what you get when $t=0$

mopsy510 · Answer

So v = 116 and h=101?

anonymous · Answer

yes

mopsy510 · Answer

So the 0 on the bottom doesnt do anything?

anonymous · Answer

it is just notation for the initial velocity and the initial height

mopsy510 · Answer

Ohh ok

anonymous · Answer

not like an exponent, just means what you get if $t=0$ in other words when you start counting

mopsy510 · Answer

So now i substitute t for 0?
