1.选择题(共5题)

1.

在平直公路上,汽车由静止开始作匀加速运动,当速度达到vm后立即关闭发动机直到停止,运动过程的v﹣t图象如图所示,设汽车的牵引力为F,摩擦力为f,全过程中牵引力做功W1,克服摩擦力做功W2,则(   )

2.

如图所示为某直升飞机的俯视图,该直升机两侧均装有等高的照明发射管,当飞机悬停时发射方向与飞行方向垂直,测得照明弹发射速度大小为v,现直升机以速率v保持与水平地面固定高度差做匀速直线飞行,每隔△t时间按下发射开关,不计空气阻力,且△t远小于照明弹在空中运动的时间,则(   )

3.

如图,竖直平面内的轨道Ⅰ和Ⅱ都由两段直杆连接而成,两轨道长度相等.用相同的水平恒力将穿在轨道最低点B的静止小球,分别沿Ⅰ和Ⅱ推至最高点A,所需时间分别为t1、t2;动能增量分别为△Ek1、△Ek2.假定球在经过轨道转折点前后速度大小不变,且球与Ⅰ、Ⅱ轨道间的动摩擦因数相等,则(   )

4.

如图所示,长为L的硬杆A一端固定一个质量为m的小球B,另一端固定在水平转轴O上,硬杆可绕转轴O在竖直平面内缓慢转动.则在硬杆与水平方向的夹角α从90°减小到0°的过程中,下列说法正确的是(   )

5.

如图所示,固定在竖直平面内倾角为θ=37°的直轨道AB,与倾角可调的足够长的直轨道BC顺滑连接.现将一质量m=0.1kg的小物块,从高为h1=0.60m处静止释放,沿轨道AB滑下,并滑上倾角也为370的轨道BC,所能达到的最大高度是h2=0.30m.若物块与两轨道间的动摩擦因数相同,不计空气阻力及连接处的能量损失.已知sin37°=0.6,cos37°=0.8,求:
