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

A 235 m tall tower is built on the equator. Due to the rotation of the earth, how much faster does a point at the top of the tower move than a point at the bottom (in m/s)?

2. Relevant equations

v=w*r (w is omega)

3. The attempt at a solution

So it didnt give me the radius of the earth but the previous problem said it was 6400 km so i used that and converted 365 days to seconds and got 31536000. Next i tried to find the velocity of the earth in m/s so 6400km= 6400000 m. 6400000m/31536000s. i get 0.2029426687. i do the same thing but at 235 to the radius and i get 0.2029426687. I next found the difference and get 7.45*10^{-6}. Its not right i dont know what im doing wrong...
