Answer:
The ball of mass of 0.52 kg
Step-by-step explanation:
By the second law of Newton, we get that the acceleration is equal to
a = F/m
Where F is the applied force and m is the mass.
So, the acceleration for each ball is equal to
For the ball with a mass of 0.52 kg
a = 26 N/0.52 kg
a = 50 m/s²
For the ball with a mass of 0.78 kg
a = 26 N/0.78 kg
a = 33.33 m/s²
Therefore, the ball with the greater acceleration is the ball with a mass equal to 0.52 kg
