Response:
 
   in the given problem the radius of solid cylinder must be given
   mass m = 14.0 kg
   speed of the centre of mass v = 10.0 m / s
(a)
   the translational kinetic energy will be      
   KET = (1 / 2) m v2
            = ......... J
(b)
   the rotational kinetic energy will be      
   KER = (1 / 2) I ω2
            = ........ J
   where ω = v / r
(c)
   the total energy is
   E = KET + KER
      = ........ J
