an object of mass 30kg is falling in air and experiences a force due to air resistance 50N. (a). determine the net force acting on the object and (b). calculate the acceleration of the object

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.
