In the winter sport of curl- ing, two teams alternate sliding 20 kg stones on an icy surface in an attempt to end up with the stone closest to the center of a target painted on the ice. Dur- ing one turn, a player releases a stone that travels 27.9 m before coming to rest. The friction force acting on the stone is 2.0 N. What was the speed of the stone when the player released it? 10. Il The forces in Figure P5.10 are acting on a 2.0 kg object. What is a,, the x-component of the object's acceleration?
