Can I get the solution for this Engineering physics problems? Subject is Classical Mechanics.

The image posted below is the question, and I also put a link for the needed textbook. the photo tells you what the question is and what you need to do.

1) Solve the orbital equation of motion for an inverse cube law force, F(r) = - -, for the three different cases below. For each one, solve the transformed equation of motion for u = = and include a qualitative description of the orbit. a. K 2) A particle moves in a circular orbit due to a central force given by F(r) = - . If the value of k instantaneously changes to k' = = , show that the orbit becomes parabolic. 3) Find the force law for a central-force field that allows a particle to move in the spiral orbit, r = k02, where k is a constant. 4) The Yukawa potential, which is useful in atomic and nuclear physics calculations, incorporates an exponential decay that decreases the range of the Coulomb potential. The Yukawa potential can be written as: k V (r) = - a-r/a r Find a particle's trajectory in a bound orbit of the Yukawa potential to first order in
