Drawing velocity time graphs from distance-time graphs

AI Thread Summary
To draw a velocity-time (VT) graph from a distance-time (DT) graph, calculate the velocity using the formula v = Δs/Δt, where Δs is the change in distance and Δt is the change in time. For unit conversions, to convert 175 kg·m/h² to g·cm/s², multiply by conversion factors that allow for cancellation of units. It's essential to maintain the integrity of the units by creating "1" from the target units in the numerator and existing units in the denominator. This method ensures accurate conversions step by step. Understanding these principles will facilitate both graph drawing and unit conversions effectively.

Can someone please tell me how to draw a VT graph from this DT graph? Thanks.

Edit: Sorry, one more question. This is about unit conversions though. How do I convert 175 kg x m/h2 to g x cm/s2?

Not being able to see your graph, I can tell you this. Obtain the velocity (velocities?) from your first graph through v=\frac{\Delta s}{\Delta t}. Can you go from here?
 
The trick in units conversions is to keep multiplying by one at each step. Just make your "1" special by putting the target units in the numerator and the existing units in the denominator, and cancel units that show up in both the numerator and denominator of the product. Like if you want to convert 175kg to g,

175kg * (1000g/1kg) = etc.

Or if you want to convert hours^2 to seconds^2,

1hour^2 * (3600seconds/hour)^2 = etc.

Does that make sense?
 

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...
