1.An airplane is flying with velocity (152, 0) m/s. It is accelerated in the x direction by its propeller at 8.92 m/s2 and in the negative y direction by a strong downdraft at 1.21 m/s2. What is the airplane's velocity after 4.30 seconds?

2.An electron starts at rest. Gravity accelerates the electron in the negative y direction at 9.80 m/s2 while an electric field accelerates it in the positive x direction at 3.80×106 m/s2. Find its velocity 2.45 s after it starts to move.

If I drown the egg in a bowl of vinegar first. Then what happens to the egg after 24hours?
Then I'll wash the egg after that and dip it into syrup for 24hours, what happens to that egg?
Finally, at last i wash the egg and drown it into water for 24hours...then what happens to the egg?

PS: There is only one egg involved. After the first step, i was told by my friends in my Biology class that the shell was supposed to dissolve but my experiment at home came out totally different. My assignment is due tomorrow, please somebody tell me the outcomes of the experiment.
