一、利用抛物线方程求解平抛运动问题平抛物体运动的轨迹是一条抛物线,如果能够巧妙的运用抛物线方程来解平抛物体的运动问题,往往会使问题更简单。例1如图1所示,从离地面高为H的A点平抛一物体甲,其水平射程为2s。在A点正上方且离地面高为2H的B点,以相同方向平抛另一物体乙,其水平射程为s。两物 First, the use of parabolic equation to solve the problem of flat throwing motion Flat trajectory of the object is a parabolic trajectory, parabolic equation clever parabolic equation to solve the problem of motion, often make the problem easier. Example 1 As shown in Figure 1, an object A is flattened from point A, which is H above ground level, with a horizontal range of 2s. At point A just above point A and point B high above the ground, throw another object B in the same direction, with a horizontal range of s. Two things
