i need help with radial acceleration?? physics please ...
Mar 30, 2012· here are two numbers i have already A grinding wheel m in diameter rotates at 2200 rpm. (a) Calculate its angular velocity in rad/s. rad/s (b) What are the linear speed and acceleration of a point on the edge of the grinding wheel? m/s (c) radial acceleration m/s2 i need help with c really bad i cant figure it out
