A physics student playing with an air hockey table (frictionless surface) finds that if she gives the puck a velocityof 3.80m/s along the length(1.75m) of the table at one end, by thetime it has reached the other end the puck has drifted 2.50cm tothe right but stillhas a velocity component along the lengthof3.80m/s. She correctly concludes that the table is not leveland correctly calculates its inclination from the aboveinformation. What is the angle of inclination?
