when you're done using an electric mixer, you can get most of the batter off the beaters by lifting them out of the batter with the motor running at a high enough speed. Let's imagine, to make things easier to visualize, that we instead have a piece of tape stuck to one of the beaters.
1) explian why static friction has no effect on whether or not the tape files off

2) suppose you find that the tape doesn't fly off when the motor is on a low speed, but speeding it up does cause it to fly off, why would the greater speed change things

Hi viviseraph00! Welcome to PF! :smile:

We can't answer the questions for you, but here's a hint to get you started …

what are the names and directions of all the forces involved? :wink:
