PLEASE SHOW WORK STEP BY STEP VERY CLEARLY, THANK YOU.

Problem 5 Someone standing at a train station notices raindrops falling vertically down at a speed of 5.0 m/'s relative to the ground. When the train moves at a constant velocity, a passenger in the train observes the raindrops make an angle of 25" when they move past a window, see diagram below. 25 URJG = velocity of the Raindrops relative to the Ground TTIG = velocity of the Train relative to the Ground. URIT = velocity of the Raindrops relative to the Train. (a) Write down an appropriate relative velocity equation, using the notation above. (b) How would you have to sketch the relative velocity equation, as a vector diagram. (c) How fast is the train moving
