由江苏省南通农业学校主编的全国中等农业学校《物理》教材第45页,在讲牛顿运动定律的应用时,有这样一道例题. 例题1 一个原来静止的物体,质量是7.0kg,受到14N的力的作用,求物体的加速度和5.0s末的速度.
At the 45th page of the “Physics” textbook of the National Secondary Agricultural School edited by the Nantong Agricultural School of Jiangsu Province, there is such an example when it comes to the application of Newton’s laws of motion. Example 1 An original stationary object with a mass of 7.0kg and 14N The role of force, seeking the acceleration of the object and the speed of the end of 5.0s.
