A 1.30 kg toaster is not plugged in. The coefficient of static friction between the toaster and a horizontal countertop is 0.400. To make the toaster start moving you carelessly pull on its electric cord.
(a) For the cord tension to be as small as possible, you should pull at what angle above the horizontal?
(b) With this angle, how large must the tension be?
This is incredibly straight forward, what do you need help with? I certainly will be happy to critique your thinking.
