I believe the answer to the first question is the golf ball because it requires less energy to move it so it will move faster than the bowling ball will with less energy. For the second question I could be wrong but I think the bowling ball has more kinetic energy because according to the equation KE= 0.5*m* x^{2} where KE represents the kinetic energy the m is the mass and x is the speed of the object the bowling ball will have more energy.
