3. Suppose the tern travels 1.70 * 104 km south, only to encounter bad weather. Instead of trying to fly around the storm, the tern turns around and travels 6.00 * 102 km north to wait out the storm. It then turns around again
immediately and flies 1.44 * 104 km south to Antarctica. What are the tern's average speed and velocity if it
makes this trip in 122 days?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
