answer? are you an answer grazer?
find the horizontal and vertical components of the initial velocity.
vertical=700*sin30=350m/s
hf=hi+vi*t-4.9t^2
0=200+350*t-4.9t^2
put that quadratic in standard form
ax^2 + bx + c=0
and solve for t with the quadratic equation
how long will it take a bullet fired from a cliff at an initial velocity of 700m per second at an angle of 30 Degree below the horizontal to reach the ground 200m below?answer
