an egg is thrown directly upward so that it remains in the air for 10 seconds.what is the initial velocity of the egg?

Answer 1

well, let's do the first half of the problem, upward, symmetrical velocity profile during fall
g = -9.81 m/s^2
v = Vi - g t

v = Vi - 9.81 t
v = 0 at top in 5 seconds
0 = Vi - 9.81(5)
Vi = 49 m/s
