Question: The acceleration a of a cart sliding down a frictionless incline with slope 0 is expected to be gsin O. To test this, a student measures the acceleration a of a cart on an incline for several different values of 0; she also calculates the corres-ponding expected accelerations gsin 0 for each 0 and obtains the results shown in Table. Add a column to the table to show the discrepancies a - gsin 0 and their uncertainties. Do the results confirm that a is given by gsin 0? If not, can you suggest a reason they do not?
