A textbook of mass 2.10 kg rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley whose diameter is 0.190 m, to a hanging book with mass 2.97 kg. The system is released from rest, and the books are observed to move a distance 1.15 m over a time interval of 0.820 s.
a. What is the tension in the part of the cord attached to the textbook?
b. What is the tension in the part of the cord attached to the book?
c. What is the moment of inertia of the pulley about its rotation axis?
Take the free fall acceleration to be g = 9.80m/s2

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.
