I had this question on a quiz today and I could not figure itout. "You are in a train traveling due east and rain fallingoutside is also blowing east. If you observe the rainfalling at 30 degrees from the horizontal how fast is the trainmoving?" I will rate 10 for insight to this problem.

Explanation / Answer
The motion of falling rain and the moving train make an angle with the horizontal.By the right angled triangle formed bythe normal,falling rain and moving train we get cos = (vt/vr) where vt and vr are the velocities ofthe train and rain. or vt = vr * cos
