A group of students collected the data shown below while attempting to measure the coefficient of static friction (of course, it looks like this group varied the amount of mass sitting on the block with each trial - this is not recommended). Nonetheless, what is their average coefficient of static friction?
Trial 1- mass of block (g)= 105. hanging mass (kg)=0.053
trial 2- 165g, 0.081kg
trial 3- 220g, 0.118kg
trial4- 280g, 0.149 kg
trial 5- 315g, 0.180 kg
trial 6- 385g, 0.198 kg
