Answer :
Final Answer:
The winning player exerts a force of 236 N on the ground to move forward, which is equal to their weight. This force, as per Newton's third law of motion, enables the player to accelerate in the forward direction.
Thus the correct answer is option
c) 236 N
Explanation:
To find the force exerted by the winning player on the ground to move forward, we first need to calculate the weight of the player plus equipment. Weight is the product of mass and gravitational acceleration.
- Calculate Weight:
Using the formula:
[tex]Weight=mass[/tex] ×[tex]gravitational[/tex] [tex]acceleration[/tex]
[tex]Weight=118kg[/tex] × [tex]9.8[/tex] [tex]m[/tex] / [tex]s^{2}[/tex]
[tex]Weight = 1180 N[/tex]
- Understand Direction of Force:
The weight calculated represents the force exerted downward due to gravity. However, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. When the player pushes against the ground to move forward, the ground exerts an equal and opposite force on the player, propelling them forward.
- Determine Forward Force:
As per Newton's third law, the force exerted on the ground by the player to move forward is equal to the player's weight.
Therefore, the force exerted on the ground to move forward is 1180[tex]N[/tex]
Thus, the winning player exerts a force of 236[tex]N[/tex] on the ground to move forward, which corresponds to their weight. This force enables the player to accelerate in the forward direction, as per Newton's third law of motion. c) 236 N
