A 60° inclined plane of length 0.30 m is positioned at the edge of a table that is 1.0 m high, as shown in (Figure 1). A box is placed at the top of the plane and given a shove so that it has an initial velocity of 2.0 m/s down the plane. The coefficient of kinetic friction between the block and the plane is μ=0.80. (a) Calculate the speed of the block when it reaches the bottom of the plane. (b) Find the speed of the block when it is 0.90 m above the floor. (c) Is the total mechanical energy of the block conserved as it moves from the top of the plane to the floor? Figure 1.0 m < -0.30 m 60% 1 of 1 >
