The correct response is:

**It changes both the direction and the speed of the ball.**

The force applied by the tennis racket on the ball alters both its velocity (speed and direction) as the ball is hit.

The best response is:

**The force will cause a change in the momentum of the object.**

This statement accurately reflects the effect of a net force on a moving object, as force is related to the change in momentum according to Newton's second law (F = ma). Changes in momentum can result from changes in speed, direction, or both.

The correct response is:

**the state of motion of an object with mass.**

Momentum is defined as the product of an object's mass and its velocity, which describes its state of motion. More formally, momentum (p) is given by the equation \( p = m \cdot v \), where \( m \) is mass and \( v \) is velocity.
