In an experiment designed to investigate the frictional forces between bodies, a force was applied to a block of wood lying on a flat metal surface, as shown. Applied force Block of wood It was observed that a minimum force was needed to move the block. The minimum force Fmin was measured for different blocks made of the same wood but with different masses M. The results of the experiment are shown in the table. M (kg) Fmin (N) 0.52 0.58 0.64 0.75 0.88 1.01 1.21 3.1 3.6 3.9 4.4 5.2 6.2 7.4 (a) Plot a graph of Fmin against M. (b) Use a linear regression analysis to fit the best straight line through the data points.
