    Center of Mass of a System Problem

    Homework Statement From an inertial reference frame S, the vector position of a particle of mass m1 = 1kg is given by r1(t)=(txhat - t^2yhat)m. The vector position of a particle m2=2m1 is given by r2=(t)=(txhat +t^3yhat)m Assume t=1second Find the position, the velocity and the...

    What does it mean for a particle to be free?

    Particle #1's motion along the y-direction is -t^2. Would this mean that it is not free?

    What does it mean for a particle to be free?

    Homework Statement From an inertial reference frame S, the vector position of a particle of mass m1 = 1kg is given by r1(t)=(tx-hat - t^2y-hat)m. The vector position of a particle m2=2m1 is given by r2=(t)=(tx-hat +t^3y-hat)m Is particle #1 free along the y-direction? Explain...

    Calculating angular speed out of tangential speed

    Homework Statement A particle A is moving at constant tangential speed v1 = 2m/s on a circumference of radius r1 = 5m. Particle B is performing a uniform circular motion on a circumference whose radius is r2 = (2)r1. Find the tangential speed of v2 of particle B assuming that the angular...
