Curling is a game similar to lawn bowling except it is played on ice and instead of rolling balls on the lawn, stones are slid along ice. A curler slides a stone across a sheet of ice with an initial speed vi in the positive x direction. The coefficient of kinetic friction between the stone and the curling lane is k. Express your answers in terms of vi, k, and g only. a. What is the acceleration of the stone as it slides down the lane? b. What distance does the curling stone travel?
