What is the definition of impulse in physics?

• The change in velocity of an object.

• The product of force and the time duration over which it acts.

• The energy stored in an object due to its position.

• The rate of change of momentum.

A 2-kg ball bounce traveling at 10 m/s towards a wall, bounces off a wall with a resultant speed of 5 m/s going in the opposite direction. If the ball was in contact with the wall for 0.1 seconds, what was the average force exerted by the wall on the ball?

• 300 N

• 100 N

• 30 N

• No one knows.
