2. Consider the force F shown in the drawing. This force acts on an object that can move along the F positive or negative x axis, or along the positive or negative y axis. The work done by this force is positive when the displacement of the object is along the axis: (a)-x, -y (b)-x, +y (c) +x, +y circular pat What enabl is above po by the tens energy gravitation axis or along the Section 6 and the...

When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with a massive 26 kg the acceleration of the object is 3 m/s^2. This is the same force acts upon another object with mass is 39 kg what is the objects acceleration.
