Question
Part B: Incline the track by raising one end until once started the block will slide down the incline with constant velocity. On the diagram draw and label the force vectors acting on the mass when at the angle where the block slides with constant velocity once started. Using Newton's SecondLaw.derivethe equationfor..intermsofe. Determine the value of ,and find th percent difference between theory and experiment. -1 Change the area in contact with the plane by turning the block on its side and repeat the experiment. Again calculate the coefficient of friction and compare with the average value calculated previously in part A. "Comment on the effect of area on the coefficient P 500g bar on top of the block (use Scotch tape to hold the mass in place) and repeat the experiment, again calculating the coefficient of friction "Comment on the effect of area on the coefficient Place aExplanation / Answer
According to the concept of the newtron laws
coefficcient of friction =tan(theta)
