如图所示是长度为L=8.0m水平传送带,其皮带轮的直径为d=0.40m,传送带上部距地面的高度为h=0.80m。一个旅行包(视为质点)以v0=10m/s的初速度从左端滑上传送带。旅行包与皮带间的动摩擦因数μ=0.60。g取10m/s2。求:
(1)若传送带静止,旅行包滑到B端时,若没有人取包,旅行包将从B端滑落到地面上,则包的落地点距B端的水平距离为多少?
(2)当皮带轮顺时针匀速转动,其角速度为ω0="20" rad/s时,求旅行包在皮带上运动的时间与旅行包落地时的速度;
(3)设皮带轮以不同的角速度顺时针匀速转动,画出旅行包落地点距B端的水平距离s随角速度ω变化的图象(ω的取值范围从0到100 rad/s)。
