Question

un) Ia the Newton's Second Law for Rotation Lab, a solis disk wheeli rokael (40 pointa)1 s, a torque produced by a hanging weight altachod to a string wapped asound the dem er the spider holkding the disk wheel. Angular acceleration in determined by mrg the time required for the disk wheel to undergo its second revoution aftes belineg (A-θ 1rev). The torque exerted on the disk whsel by the string's unwin an thea- elonoe experiment The radius of the dran is r 2.43cm ox a hypothe r (N m) Torque vs. angulat acceleration 0.02 0.01 a (rad/) 0.4 a. (20 points) In addition to the data plotted above, there is ose additional data point The hanging mass is 0.080 kg and the photogate time is 2.857 s. Calculate the corresponding values of a and r for this data point and plot that point in the graph above. 0.1 0.2 3837,5
