What angle should the arrow make with the horizontal as it is being shot?
29.September, 2009
An archer wishes to shoot an arrow at a target at eye level a distance of 42.5 m away. If the initial speed imparted to the arrow is 75.0 m/s, what angle should the arrow make with the horizontal as it is being shot?
Please let me know how to solve this, thanks!
It depends a great deal on the seemingly unimportant variables you did not include in the equation. What is the amount of force applied to the arrow; direction and speed of wind, if any; physical weight of the arrow; dynamic balance of the arrow (how far from front or rear is the actual point of balance)? There are other variables as well, and they must all be included in the equation.
The answer to the question, as it is now worded, is "somewhere between 0 and 90 degrees above horizontal". It might be 1/2 a degree, and it might be 40 degrees, it might be 0 degrees — depending on the variables which are not included in the formulation of the question.
