Answer:
Mass of the object is 8.5 kg.
Step-by-step explanation:
Given that,
Acceleration of the object is 4 m/s^2
Force applied to the object, F = 34 N
To find :
The mass of the object.
Solve :
Let m is the mass of the ball. The Newton's second law of motion defines the magnitude of force acting on an object.



m = 8.5 kg
Therefore, the mass of the ball is 8.5 kg.
