PLEASE HELP!!!!

If multiple forces are acting on an object, which statement is always true? (1 point)
a. the acceleration will be directed in the direction of the gravitational force
b. a. the acceleration will be directed in the direction of the applied force
c. the acceleration will be directed in the direction of the net force
d. the acceleration will be directed in the direction of the normal force

Answer: C

Step-by-step explanation:

The answer is choice C.

The sum of the vectors is the resultant vector, which is where the net force is directed.

An example would be if you had a ball rolling on a table and you bumped the ball perpendicular to its initial velocity, then the ball would move at a diagonal angle rather than move straight in the direction where you bumped it.

Acceleration is the change in velocity over time, so the acceleration vector tells us how the velocity's direction is changing.

Answer:

Step-by-step explanation:

1.) If multiple forces are acting on an object, which statement is always true?

Answer: The acceleration will be directed in the direction of the net force.

2.) If a ball is accelerating down through the air with no horizontal motion, what must be true about the net forces acting on the ball?

Answer: The gravitational force is greater than the drag.

3.) A boy who exerts a 300-N force on the ice of a skating rink is pulled by his friend with a force of 75 N, causing the boy to accelerate across the ice. If drag and the friction from the ice apply a force of 5 N on the boy, what is the magnitude of the net force acting on him?

Answer: 70 N

4.) Four friends push on the same block in different directions. Allie pushes on the block to the north with a force of 18 N. Bill pushes on the block to the east with a force of 14 N. Chris pushes on the block to south with a force of 23 N. Debra pushes on the block to the west with a force of 20 N. Assuming it does not move vertically, in which directions will the block move?

Answer: south and west

5.) Two teams are playing tug of war. The tables show the members of each team and how much pulling force each team member applies to the rope.

If Team A pulls to the right and Team B pulls to the left, what is the total horizontal net force applied to the rope?

Answer: 20 N to the left

I hope this helps whoever needs it :))
