William Tell must split the apple atop his son's head from a distance of 27 meters. When he aims directly at the apple, the arrow is horizontal. At what angle must he aim the arrow to hit the apple if the arrow travels at a speed of 35m/sec?

#### Solution Preview

Note that 35 m/sec is only the initial speed of the arrow. When the arrow is fired at angle B above the horizontal, it has a changing upward speed, due to the downward force of gravity, and has a constant horizontal speed since the net horizontal force is zero.

For V = 35 m/sec at ...
