1. Un cuerpo describe un movimiento circular uniforme con una velocidad angular de 20 ∏rad/seg y radio 5cmsi el objeto se encuentra a un punto po a ∏/3rad de la posición de equilibrio. 2. Determinar la posición del objeto en punto p0 y la posición del objeto 0.3 seg después de haber pasado por punto po. URGENTE!!!

Madison pushes with a 210-n horizontal force on a 24-kg crate of coffee resting on a warehouse floor. the force of friction on the crate is 74 n. what is the acceleration?

When using the scientist method, which step comes last?

Two identical stars with mass m orbit around their center of mass. each orbit is circular and has radius r, so that the two stars are always on opposite sides of the circle. (a) find the gravitational force of one star on the other. (b) find the orbital speed of each star and the period of the orbit. (c) how much energy would be required to separate the two stars to infinity?
