I'm trying to do my physics homework but I am just not understanding this section on vectors. I don't even know where to begin or what equations to use. Any help would be greatly appreciated! a) On a rainy day, raindrops fall with a vertical velocity of 9.2 m/s. If a car drives through the rain at 84.0 km/hr, what is the magnitude of the velocity of the raindrops relative to the car? b)At what angle are the raindrops falling relative to the car? Assume the direction the car is headed is 0° and down is 90°.
