The bee is travelling from point A to point B in a parabolic path shown in the figure. If its tangential acceleration is expressed as a = 5t² - 16 m/s², (a) what is its velocity at any given time? (Assuming that the particle is at rest from the beginning) (b) what is the resultant acceleration if it the bee took 4 seconds to reach point B?

Please do not give solution in image format thanku If you want to do your scale model presentation in such a way that BOTH the size AND distance scaled are correct, how far apart would your squishy stress ball Moon and your answer to the previous question need to be? HINT: Multiply the diameter of the scale model Earth that you chose in the previous question by the number of Earth diameters that would fit between the Earth and the Moon.   Answer choices:   A- You'll need to put one against one wall and hold the other one across the room 240 inches or 20 feet apart   B- You will need a volunteer from the audience so you can hold them 72 inches or 9 feet apart   C- You could hold them both in front of you at 16 inches or about 1.3 feet apart   D- You'll need to tell the kids to use their powers of imagination because the separation would put one of them in the parking lot outside the science center 3600 inches or 300 feet away

Write brief notes on the following: a, the technique of estimating mean depth and mean area; and b, technical sanction.
