The hammer throw is a track-and-field event, popular in Scotland, in which a ball on a rope (the "hammer") is whirled around the thrower in a circle before being released. The goal is the send the ball as a projectile as far down the field as possible. At a track meet, the circle in which a ball is whirled by a hammer thrower is at a 45° angle to the ground. To achieve the longest distance, at what point in its tilted circular orbit should the thrower release the ball?
a. at it's lowest point
b. at it's highest point
c. halfway as it moves from it's lowest point to it's highest point
d. halfway as it moves from it's highest point to it's lowest point
