Buzz Lightyear is standing on top of a building on the planet Zook. He wishes to determine the height of the building, so he drops a stone off thebuilding and it falls for 2 seconds. Buzz knows that gravitational acceleration on Zook is 5 (m/s)/s.a) EXPLAIN how you would use the How fast method to determine the speed of the stone when it reaches the ground as well as the average speed ofthe stone during this time. Give the speed and average speed of the stone.b) EXPLAIN how you would use the How-far method to determine height of the building. Give the height of the building.Maximum number of characters (including HTML tags added by text editor): 32,000Taxr Ediser(aad characrer count)

In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5120 km away, and released. It found its way back to its nest 12.5 days after release. Part A If we place the origin in the nest and extend the +x-axis to the release point, what was the bird's average velocity for the return flight? Express your answer in meters per second. ANSWER: Vay.-x = m/s Part B What was the bird's average velocity for the whole episode, from leaving the nest to returning? Express your answer in meters per second. ANSWER: Vav. = m/s
