如图甲所示质量m＝1kg的小物块A可视为质点放在质量M＝4kg木板B的左端木板长L＝4.5m．起初AB两叠体静止于水平面上．现用一水平向左的力F作用在木板B上通过传感器测出AB两物体的加速度与外力F的变化关系如图乙所示．已知两物体与地面之间的动摩擦因数相等且最大静摩擦力等于滑动摩擦力g取10m/s2．求 1AB之间的动摩擦因数μ1及B与地面之间的动摩擦因数μ2． 2若开始时对B施加水平向左的恒力F＝29N且给A一水平向右的初速度v0＝4m/s则t＝2s时A与B的右端相距多远
如图所示两个可导热的气缸竖直放置它们的底部都由一细管连通忽略细管的容积．两气缸各有一个活塞质量分别为m1和m2活塞与气缸无摩擦．活塞的下方为理想气体上方为真空．当气体处于平衡状态时两活塞位于同一高度h．已知m1＝2mm2＝m 1在两活塞上同时各放一质量为m的物块求气体再次达到平衡后两活塞的高度差假定环境温度始终保持为T0． 2在达到上一问的终态后环境温度由T0缓慢上升到1.25T0试问在这个过程中气体对活塞做了多少功假定在气体状态变化过程中两物块均不会碰到气缸顶部．
