Q4) One of the most astonishing applications of analytical mechanics is the study of fly motion. In this example, we work on a mosquito that crawls in a spherical path on
the surface of marble of diameter (D) according to the following equations
D
= wt
= 2
0 = (cos 40 + 4)k,
where k is constant. Find the speed of the mosquito at t = 0 second where k = 1 and
at t = To seconds. Explain with a diagram, how the motion looks like.

Geologists get to play with chemistry, physics, and history! and what a history you will meet as youwork your way through the course. starting at the beginning, the textbook provides the scientifically acceptedstart of the and promises that you'll get to explore some of the evidence for that scientific view, later inthe semester. meanwhile, which is more nearly correct of the scientifically accepted view? a) the earth formed when the big bang caused older materials to fall together, about 14 billion years ago.b) the earth formed from the falling together of older materials, about 4.6 billion years ago.c) the earth formed in the big bang, about 6000 years ago.d) the earth is eternal, having been here forever and promising to be here forever.e) the earth was assembled by gigantic space beavers, which gnawed down the primordial tree of life andpiled its branches together to form the planet.
