问题 :物体以大小不变的初速度v0 沿木板向上滑动 ,若木板倾角θ不同 ,物体能上滑的距离s也不同 ,如图 1是得出的s-θ图像 ,求图中最低点P的坐标 .图 1这是一道物理情景非常熟悉但题型又较为新颖的数形结合题 ,常规解法如下 :由题中s-θ图像可知 ,当木板倾角θ=θ1=0°时 ,物体 Problem: The object slides along the board at an initial speed v0 of constant size. If the board angle θ is different, the distance at which the object can slide is also different, as shown in Figure 1 for the s-θ image. Find the lowest point in the graph. The coordinates are shown in Fig. 1. This is a combination of number and shape that is familiar to the physics scene but more novel in the question type. The conventional solution is as follows: From the s-θ image in the question, when the angle of inclination of the wood plate θ=θ1=0°, the object
