If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?  (F=ma)

• The one with a mass of .78 kg will have the greatest acceleration.
• The one with a mass of .52 kg will have the greatest acceleration.
• They will both accelerate at the same rate.
