A 0.55-kg croquet ball is initially at rest on the grass. When the ball is struck by a mallet, the average force exerted on it is 270 N.

If the ball's speed after being struck is 5.1 m/s, for what amount of time was the mallet in contact with the ball?

I solved this and got 0.0104 but mastering physics is saying that my answer is not correct.
