the mass of the ball is 0.43kg and the weight of the player is 900N.the player is at rest.whAt is the normal force exerted on the exerted?
To find the normal force exerted on the player, we need to first understand the concept of normal force. The normal force is the force exerted by a surface to support an object resting on it. It acts perpendicular to the surface and counterbalances the weight of the object.
In this scenario, the player is at rest, meaning there is no vertical acceleration. Therefore, the net force in the vertical direction is 0. This allows us to equate the weight of the player to the normal force.
Weight is calculated as the product of mass and acceleration due to gravity (W = m * g), where mass (m) is given as 900 N and acceleration due to gravity (g) is approximately 9.8 m/s^2.
Let's calculate the mass of the player:
mass = weight / acceleration due to gravity
= 900 N / 9.8 m/s^2 ≈ 91.8 kg
Now we can determine the normal force exerted on the player, which is equal to the weight:
normal force = weight = mass * acceleration due to gravity
≈ 91.8 kg * 9.8 m/s^2
≈ 899.64 N
Therefore, the normal force exerted on the player is approximately 899.64 N.
