NEWTON'S LAWS OF MOTION
Laws of Motion

270239 six forces lying in a plane and forming angles of \(60^{\circ}\) relative to one another are applied to the centre of a homogeneous sphere with a mass \(m=6 \mathrm{~kg}\). These forces are radially outward and consecutively \(1 \mathrm{~N}, 2 \mathrm{~N}, 3 \mathrm{~N}, 4 \mathrm{~N}, 5 \mathrm{~N}\) and \(6 \mathrm{~N}\). The acceleration of the sphere is
