Velocity time graph with distance and average speed

AI Thread Summary
Velocity can be determined from a graph that plots distance against time by analyzing the slope of the graph. The slope represents the instantaneous velocity at any given point on the curve. Average speed, on the other hand, is calculated by dividing total distance by total time. Understanding the relationship between distance, time, and velocity is crucial for interpreting such graphs accurately. Therefore, it is possible to derive velocity from a distance-time graph by focusing on the slope.

I know how to work out velocity once you have the graph, I'm just not sure if i can do the graph with distance and average speed.

So, can you work out velocity from a graph with distance and average speed?

Velocity is "slope" (it's the tangent line) of the distance at anyone instant.
 
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 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
