Question

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.

Step 1

**Given:**

Mass of the ball, m = 0.55 kg

Average Force on the ball, F = 270 N

Initial velocity of the ball, u = 0

Velocity of the ball after hit, v = 5.1 m/s

Step 2
