In air what is the value for speed of light
WebJul 15, 2010 · Fredrik said: The closing speed is defined as minus the rate of change of the coordinate distance. Your two objects are located at a+vt and b-ct for some a and b>a, so the coordinate distance between them at time t is (b-ct)- (a+vt)=b-a-ct-vt, and the closing speed is therefore. -d/dt (b-a-ct-vt)=c+v.
