In a laboratory model of cars skidding to a stop, dataare measured for four trials using two blocks. Theblocks have identical masses but different coefficientsof kinetic friction with a table: mk 5 0.2 and 0.8. Eachblock is launched with speed vi 5 1 m/s and slidesacross the level table as the block comes to rest. Thisprocess represents the first two trials. For the next twotrials, the procedure is repeated but the blocks arelaunched with speed vi 5 2 m/s. Rank the four trials(a) through (d) according to the stopping distancefrom largest to smallest. If the stopping distance isthe same in two cases, give them equal rank. (a) vi 51 m/s, mk 5 0.2 (b) vi 5 1 m/s, mk 5 0.8 (c) vi 5 2 m/s,mk 5 0.2 (d) vi 5 2 m/s, mk 5 0.8
