A hockey player winds up for a slap shot and swings his stick so that its motion is in a vertical circle, with the blade of the hockey stick reaching maximum speed just before he hits the puck on the ice.

Solution
The acceleration vector of the hockey stick blade, when it is parallel to the ice, points straight down. This is due to the centripetal acceleration, which always points towards the center of the circle. In this case, the circular path is vertical, so the center of the circle is straight down from the position of the hockey stick when it is parallel to the ice.
