Homework Statement
An object is thrown with velocity v from the edge of a cliff above level ground. Neglect air resistance. In order for he object to travel a maximum horizontal distance from the cliff before hitting the ground, the throw should be at an angle theta with respect to the horizontal of
A) greater than 60 degrees above the horizontal
B) greater than 45 degrees but less than 60 degrees above the horizontal
C) greater than zero but less than 45 degrees above the horizontal
D) zero
E) greater than zero but less than 45 degrees below the horizontal.
Homework Equations
Kinematics. range = Vx * flight time
The Attempt at a Solution
[/B]
I put down D with the following logic: if I have my velocity at an angle, then its horizontal component would be smaller than if the velocity is directed along an angle of theta=0. Increased horizontal component would increase its range per the equation that I typed above.
The solutions say that the answer is C. Why is this the case, and why are each of the answers that are not C incorrect?
Thanks in advance for the help!
