Help! Stuck on these 2 problems
1. Determine the motions equations of an ideal pendulum of mass m and lengh r.
2. A machine is formed by a homogenous cylinder of radio R and mass M. It rotates in its axel (frictionless). A mass by an inextensible cord (massless) is roller to cylinder. Find...
A body free fall into a viscous fluid. Calculate the dissipating speed of kinetic and potential energy during this motion into the fluid. ( suppose Yo initial height)
