A rocket is launched straight up from the side of a cliff 40m high. If the initial velocity (v) is 30 m/sec and the height (H) is given by the formula = −16² + + ℎ, find the time at which the rocket will hit the ground. * HELP PLS IM AT A TESTTT
A. 2.78sec
B. -0.90sec
C. 3.1sec
D.-0.6sec

ab will be equal to

30005

yes ok                                            

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
