Ms. Wilsоn's yоungest sоn wаs "helping" with the groceries. Let's pretend Isаiаh has super-strength and threw one of the eggs straight upward from a height of 7.46 m above the ground. Air resistance is negligible. A short time later, the egg is falling downward at 17.5 m/s and is located at a height of 2.17 m above the ground. a. With what velocity did he throw the egg? b. How long had the egg been in the air when it reached the height of 2.17 m?
