A person looking out the window of a stationary train notices that raindrops are falling vertically down at a speed of 8.7 m/s relative to the ground. When the train moves at a constant velocity, the raindrops make an angle of θ = 67° when they move past the window as the drawing shows. How fast is the train moving?
Vx = V0x +axt
The Attempt at a Solution
3.4 and 22.3 m/s are both incorrect.
Couldn't figure out how to do it since clearly you don't just use the Pythagorean Theorem... walk me through it?
