When the batter hits the ball, a net force of 1150 n, opposite to the direction of the ball's initial motion, acts on the ball for 9.0 x 10-3 s during the hit. what is the final velocity of the ball?

This question is not complete as we cannot find the velocity without knowing the mass of the ball.

Explanation:

While the question may not be complete, I could guide on what to do.

From Newton's second law of motion,

An impressed force is proportional to the rate of change of momentum.

Mathematically, this is written as

Where

is the impressed force, is the mass of the object, and are the initial and final velocities respectively.

This equation can be written as

Substituting the values from the question,

Assuming the collision is perfectly elastic, then (being perfectly elastic means it rebounds with the same initial velocity; the negative sign indicates that the rebound is opposite in direction). Thus, we have

Then the final velocity is

If is known, then you have your answer.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
