AI Thread Summary
To calculate the average force exerted by the ground during a collision, use Newton's second law, F = MΔV. The person's mass is 220 kg, and the average acceleration during the collision is 75.0 m/s². The net force acting on the person includes both their weight and the upward force from the ground. It's important to correctly apply the relevant equations to determine the average force. Understanding these principles is crucial for solving collision-related physics problems effectively.

Homework Statement



A person mass is 2.20 times 10 raised tothe second kg...he falls and hits the ground. His average accelaration over the course of the collision is 75.0 m/s squared. Find the avarage force that the ground exerts on him during collision.

Homework Equations



F=MDeltaV

That's a pretty heavy person at 220 kilos. Anyway, your relevant equation is incorrect. Try Newton's 2nd law. That will give you the net force acting on the person during the collision. The net force includes his weight down and the gound force acting up.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
