E '' W mt/t/Ww Ix-I |

l..-.---------x----------+l (a) (b) You are in your physics lab doing an experiment on spring force and friction. The mass of the block is 2.0 kg and the spring constant is 50 N/m. You slowly pull on the spring and measure that the elongation (stretch) of the spring is Ac = 0.24m when the block starts to move. (a) What is the coefficient of static friction between the block and the lab table? Give your answer to two significant figures. (b) What is the work you need to do on the spring to elongate the spring from 0 m to 0.24 m, the point when the block starts to move? You can add an optional tip or note related to the prompt like this.
