Answer :
Answer: A
Explanation:
Impact for is acting on a floor due to momentum change in a very small time period here we dont have any velocities or time period of collision . There is not enough data for calculate the answer this is the equation that we are used to perform this
F = (mV -mU) /t
The magnitude of the impact force will be 9.81 newtons. Then the correct option is D.
What is impact force?
When a force is applied to the body for a short interval of time, is known as impact force.
A1 N apple falls to the ground.
When an apple is just released then it will fall under gravity. The acceleration due to gravity is 9.81 meters per second square.
When it hits the ground the velocity of the apple will be zero.
Then the impact force will be
[tex]\rm F = \dfrac{m(U-V)}{t}\\\\F = (9.81 - 0)\\\\F = 9.81[/tex]
The magnitude of the impact force will be 9.81 newtons. Then the correct option is D.
