Finding Max Force Acting on a Moving Body Mass: A Challenge

AI Thread Summary
To find the maximum force acting on a moving body mass of 1.6 kg with varying speeds, the correct approach involves calculating the instantaneous acceleration rather than the average. The speed measurements taken at two-second intervals show an increase from 7.00 m/s to 10.50 m/s. The maximum force can be determined by identifying the greatest change in velocity over the shortest time interval, which corresponds to the highest acceleration. Using F=ma with the maximum acceleration will yield the maximum force. The discussion emphasizes the importance of instantaneous values over averages in this context.

The speed of a body mass m = 1.6 kg moving in a straight line varies smoothly. It is measured five times, at two second intervals. The values are 7.00, 7.77, 8.89, 9.80, and 10.50 (m/s). What is the maximum value of the force acting on the body?

I tried taking the average acceleration of the whole system and plugging it into F=ma but that didn't work. Then I tried finding the change in momentum but still unsuccessful.

why would the average be the maximum? :wink:
 

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 .
