رد: فيزياء .. مساااااااااااااعدة أرجوكم
شوفو دا السؤال .
0=An object moves horizontally with a constant acceleration. At time t = 0 s, the object is at x
What are the initial velocity and acceleration of the object at x = −1.5 m at time t = 3 s?
a) v0 = +2 m/s, a = +2 m/s b) v0 = −2 m/s, a = +2 m/s c) v0 = +2 m/s, a = −2 m/s
d) v0 = 1 m/s, a = −1 m/s
الاجابة دي .. بس انا تنحت مارعرفت كيف ..؟
