A rectangular block has a length that is six times its width and a height that is three times its width. The block's surfaces are all identical except for size. When the block is placed on a horizontal tabletop so that the area in contact with the table is length x width, it is found that a horizontal force of 11.5 N applied to the block is just sufficient to overcome the static friction force and cause the block to move. The block is then knocked over so that the area in contact with the table is length x height. Now, what minimum horizontal force will cause the block to move? N Explain.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 v; in the positive x direction. The coefficient of kinetic friction between the stone and the curling lane is uk. Express your answers in terms of Vi, uk, and g only. (Assume the direction of the stone's motion to be the positive direction. Do not substitute numerical values; use variables only. Indicate the direction with the sign of your answer.) (a) What is the acceleration of the stone as it slides down the lane? ax (b) What distance does the curling stone travel? DJ =
