![]() ![]() ![]() Now I turn around and start throwing the same oranges from the rear of the truck, that is backward. ![]() When I have thrown the orange in the front, adding more velocity to it, she will say it is going at (18m/s + 12m/s) 30m/s.Well, even before I throw it, she will say that the orange is moving at 18m/s such that the speed of everything on the truck.How quickly does my friend on the sidewalk say the orange is moving?.Still, they are moving 12m/s, relative to me, I can only make an orange move apart from me at 12m/s, so that is how fast I measure the orange moving away from me.If I am really not aware of what’s going on around me such that like the point that I am standing in the back of a moving truck, how quickly would I say the oranges are moving?.I am still throwing oranges forwards, correctly the same as I was throwing them before, at 12m/s. Now the truck starts to move forwards at 18m/s.Considering she will see them exactly the same way as me i.e., we are both in the same reference frame (We will discuss reference frame in the upcoming section), she will say 12m/s.If a person were standing on the footpath, how fast would she say the oranges are moving?.I know that I can throw an orange at exactly 12m/s every time. Let us say I am standing on the back of a pickup truck such that they are motionless, and I am throwing oranges forwards. ![]()
