A hot-air balloon is drifting in level flight due east at 2.5 m/s due to a light wind. The pilot suddenly notices that the balloon must gain 24 m of altitude in order to clear the top of a hill 120 m to the east. (a) How much time does the pilot have to make the altitude change without crashing into the hill? (b) What minimum, constant, upward acceleration is needed in order to clear the hill? (c) What are the horizontal and vertical components of the balloon’s velocity at the instant that it clears the top of the hill?

The drawing in the image attached shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Side 1 has an area of 1.90 m^2, Side 2 has an area of 3.90 m^2, the electric field in magnitude is around 215 N/C. Please find the electric flux magnitude through side 1 and 2 combined if the angle (theta) made between the electric field with side 2 is 30.0 degrees. Thank you.
