普通洗衣机的脱水桶以1200r/min的速度高速旋转，为避免发生人身伤害事故，脱水机构都装有安全制动系统．如图所示为脱水制动示意图，该系统由脱水桶盖板、制动钢丝、刹车制动盘等组成，刹车盘与脱水筒共轴转动．当脱水桶运转时，如果打开脱水桶盖，则该系统便产生制动作用．安全制动系统的作用有两个：一是将脱水电动机的电源自动切断；二是刹车带自动紧压在刹车盘上，使脱水桶迅速停止转动．

若脱水桶的半径为9cm，刹车盘的半径为6cm，打开脱水桶盖到脱水桶停止共转了50圈（设为均匀减速），若衣服和桶的质量为3kg（可以认为质量全部分布在脱水桶桶壁上，刹车盘的质量不计）．试计算：

（1）打开脱水筒盖的瞬间，贴在脱水筒筒壁上的衣服运动的线速度；

（2）刹车盘边缘上的某点在这一过程中的路程；

（3）刹车带上的平均摩擦力的大小．
