A box mass 55.0 kg is moving along the x-axis attached to a uniform spring of mass 6.50 kg and force constant 2500 N/m. Calculate the angular frequency of the box by considering effect of mass of the spring. (a) 6.74 rad/s (b) 6.61 rad/s (с) 6.37 гad/s (d) 6.55 rad/s A box mass 55.0 kg is moving along the x-axis attached to a uniform spring of mass 6.50 kg and force constant 2500 N/m.
