The uniform spool is supported on small rollers at A and B. Determine the constant force P that must be applied to the cable in order to unwind 8 m of cable in 4 s starting from rest. Also calculate the normal forces on the spool at A and B during this time. The spool has a mass of 60 kg and a radius of gyration about 0 of k0 = 0.65 m. For the calculation neglect the mass of the cable and the mass of the rollers at A and B.
