How do I accurately enter values in Mastering Physics for kinematics problems?

AI Thread Summary
Accurate entry of values in Mastering Physics for kinematics problems is crucial to avoid losing marks. The user initially struggled with how to format their answers, specifically whether to enter 138 as 1.4*10^2 or 14*10. They ultimately resolved the formatting issue but expressed frustration over losing 0.3% of their grade due to the entry error. The discussion highlights the importance of precision in numerical input in educational platforms. Understanding how grading impacts overall performance is also emphasized.

The Attempt at a Solution


by the second derivative a = 30t-3
a(4.7)=138
do I enter as 14 * 10 or 1.4*10^2 I don't want to lose anymore marks because I don't know how to enter it
also average accelaration is 67.5 i enter it as 68?

Never mind I got it write (1.4*10^2 ,68)but I lost .3% of the grade :(((

Oh no! Now you won't get above 99.7%
 
actually the home work only cover 10% of the total grade and since we cover 10 sub section every section covers 10% of the 10% of the total grade
so I lost .3%of 10% of 10% of the total grade so I only can take up to 99.997 ! what if someone takes 99.998 lol ( to mods I wasn't spaming I was just practicing percentage problem :) )
 

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 .

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...
