例题一个做匀加速直线运动的物体,在连续两个5s 内通过的位移分别是30m 和80m,求此物体运动的初速度和加速度各是多大?解法1 用基本公式画出题设运动过程的示意图,如图1所示,因题设中涉及位移和时间等物理量,故选择位 Example: An object that performs a uniform acceleration linear motion and has a displacement of 30m and 80m within two consecutive 5s, and how large is the initial velocity and acceleration of the object’s motion? Solution 1 Use the basic formula to draw the title of the motion process. Schematic diagram, as shown in Figure 1, because the title design involves physical quantities such as displacement and time, so select bits
