I'm having some trouble with the below vector question. I've got an answer although I'm not sure if it is correct or not.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A car travels due east with a speed of 40 kph. Rain drops are falling at a constant speed vertically with respect to Earth. The traces of the rain on the side windows of the car make an angle of 50 degrees with the vertical. Find the velocity of the rain in the following reference frames: a) the car b) the Earth

2. Relevant equations

x = VxCosTheta

Y = VySinTheta

Trig

3. The attempt at a solution

X = (40)/(3.6 * tan 50) = 17

Y = (40)/(3.6 * sin 50) = 14.5

Would it be a) 17 m/s b) 14.5m/s ?
