A car travels due east with a speed of 35.0 km/h. Raindrops are falling at a constant speed vertically with respect to the Earth. The traces of the rain on the side windows of the car make an angle of 55.0° with the vertical. Find the velocity of the rain with respect to the following reference frames. 1. the car : ___m/s 2. the Earth: ___m/s I don't know how to solve this problem. I am bad at physics and I can't find any formulas to save me. If some could help walk me through it, help me, or point me in the right direction, that'd be great. Thanks.
