14.保龄球运动既可以锻炼身体,又可以缓解心理压力,而且老少咸宜,广受大众的喜爱.某同学设想了如下过程来模拟--次保龄球的投掷、运行、撞击的训练过程.如图所示,将一质量为M=2.8kg的保龄球从A点开始由静止向前掷出,球沿曲线运动,脱手后,在B点以v0=6m/s的速度切入水平球道.球做直线运动经=4s时间后在C点与质量为m=1.4kg的球瓶发生正碰.已知在A点时保龄球的下沿距离球道表面的高度为h=1m,保龄球在球道上运动时受到的阻力恒为重力的k=0.05倍,取10m/s^2,,忽略空气阻力,忽略保龄球的滚动,球与球瓶的碰撞时间极短,碰撞过程没有机械能损失,球与球均可看成质点.求:

12.如图甲所示的电路中,电源电压为3V,闭合开关S,电压表测量灯泡3V,两端的电压;此时电压表的示数如图乙所示,则灯泡L两端的电压为L1V。13.如图所示,这是电阻甲和乙的U-I图像,由图像可知,甲的阻值为将甲和乙串

伽利略曾研究过平抛运动,他推断:从同一炮台水平发射的炮弹,如果不受空气阻力,不论它们能射多远,在空中飞行的时间都一样。这实际上揭示了平抛物体AA.在水平方向上做匀速直线运动B.在竖直方向上做自由落体运动C.在下落过程中机械能守恒
