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.

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

In which of the following would the particles move most rapidly? a. ice at -20 °c b. water at 20 °c c. steam at 110 °c d. boiling water e. ice at 0 °c
