Question
A cannon is fired at 30 degrees above the horizontal with a velocity of 200 m/s from the edge of a 125 m high cliff. Calculate where the cannonball lands on the level plain below.
Answers
just plug your numbers into
y = tanθ x - g/(2(v cosθ)^2) x^2
and solve for x when y = -125
y = tanθ x - g/(2(v cosθ)^2) x^2
and solve for x when y = -125
