1. The problem statement, all variables and given/known data The tips of the blades in a food blender are moving with a speed of 15 m/s in a circle that has a radius of 0.052m. How much time does it take for the blades to make on revolution? 2. Relevant equations T=(2XpiXr)/T T: period of time it takes to complete one cycle 3. The attempt at a solution I tried using the equation under "relevant equations" and got 0.02seconds as an answer. This is wrong but I don't know what other equation to use..
