Top Problems Lecture Series for AIR 1 – 1000 in IIT JEE Advanced
Hello friends
here is the first physics video lecture on relative motion of two airplanes . The video is of level 5 out of 10.
Problem Question is
Airplane A & B are flying with constant velocity in the same vertical plane at angle 30o & 60o w.r.t. the horizontal respectively as shown in figure. The speed of A is 100√3 ms-1. At time t = 0 an observer in A finds B at a distance of 500 m. This observer sees B moving with a constant velocity perpendicular to the line of motion of A. If at t = t0 , A just escapes being hit by B, t0 in seconds is __
