An 1 kg toaster is not plugged in. The coefficient of static friction between the toaster and a horizontal counter-top is 0.3.
To make the toaster star moving, you carefully pull on its electric cord.
For the cord tension to be as small as possible, you should pull at what angle above the horizontal?
State your answer to the nearest tenth of a degree.
