A physics student playing with an air hockey table (a frictionless surface) finds that if she gives the puck a velocity of 5.30 m/s along the length (2.80 m) of the table at one end, by the time it has reached the other end the puck has drifted 5.19 cm to the right but still has a velocity component along the length of 5.30 m/s. She correctly concludes that the table is not level and correctly calculates its inclination from the above information. What is the angle of inclination?
