Happy to see its human, a dog excited wags its tail in simple harmonic motion. The tail is approximately much like a rigid rod rotating about one end, is 38 cm long, and and rotates from the left side to the right side (sweeping 180 degrees) and back 2.2 times per second. What is the maximum acceleration at the tip of its tail?

Report the value in m/s2 rounded to the nearest whole number.
