Answer:

9kg

Explanation:

According to Newton's second law, Force=Mass x Acceleration.

Since we have the Force and the Acceleration, we can plug the values in and solve for mass using this equation:

90N = Mass x 10m/s

Divide both sides by 10:

90/10=Mass x 10/10

Mass = 9

The Mass of the object is 9kg.
