Compute all parts of given question:
Question: When a train's velocity is 12.0 m/s eastward, raindrops that are falling vertically with respect to the earth make traces that are inclined 30.0 degrees to the vertical on the windows of the train.
Part A: What is the horizontal component of a drop's velocity with respect to the earth?
Part B: What is the horizontal component of a drop's velocity with respect to the train?
Part C: What is the magnitude of the velocity of the raindrop with respect to the earth?
Part D: What is the magnitude of the velocity of the raindrop with respect to the train?
It'd be really helpful if you could show all steps of your work. Thanks.
