<h3>Answer</h3>
B)
FN - mgcosФ = 0
<h3>Explanation</h3>
Given the mass of an object, forces that will be acting on it are as following
- Force due to gravity (weight) of an object
- The Normal force (the perpendicular force from that the inclined surface exerts on the object)
- Any frictional forces (due to static friction or kinetic friction, if applicable) along the incline
- The corresponding force component along the incline (downhill force due to gravity)
Force due to gravity = -mgcosΔ
Normal force = fN
Frictional force = -f
force applied forward = mgsinΔ
Horizontal force = mgsinΔ - f
vertical force = fN - mgcosΔ

Answer:
Force of the ball against the bat
Explanation:
Newton's third law of motion states that for every action, there is an equal and opposite reaction. When a player hits a ball with a bat, the force the player exerted on the ball through the bat gave the ball a push force in the forward direction. This is an action force. Now that an action has been initiated, there must be a reaction according to Newton's third law of motion. The magnitude of the force on the ball equals the magnitude of the force on the bat. The direction of the force on the ball is opposite to the direction of the force on the ball. The ball will give the bat an equal and opposite force trying to push the bat backward by resisting the impact of the bat. This is the reaction. The ball will only move if the applied force is able to overcome the resisting force by the bat.
Where;
is the action force of the bat against the ball.
is the equal and opposite reaction force of the ball towards the ball.
