The force acting on the object can be calculated using Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration. In this case, the mass of the object is 10 kg and the acceleration is 15.55 m/s².

$$F = ma$$

Where,

F = Force in Newtons (N)

m = Mass in kilograms (kg)

a = Acceleration in meters per second squared (m/s²)

Substituting the given values:

$$F = (10 kg)(15.55 m/s²)$$

$$F = 155.5 N$$

Therefore, the force acting on the 10 kg object is 155.5 N.
