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)
