Answer:

the dish's acceleration is 0.375 m/s^2.

Explanation:

Recall the formula from Newton's 2nd Law:

Force = mass x acceleration.

Since we know the force in the direction of the movement (0.15 N), and we know the mass of the object (0.4 kg) , its acceleration is given by:

acceleration = force / mass = 0.15 N / 0.4 kg = 0.375 m/s^2
