Gravitational potential energy homework

AI Thread Summary
The gravitational potential energy of a 65 kg diver on a 10.0 m diving platform is calculated using the formula Ep = mgh, resulting in 6370 Joules or 6.37 kilojoules. To determine the diver's speed upon striking the water, conservation of energy principles should be applied, linking potential energy to kinetic energy. The discussion emphasizes the relationship between speed and kinetic energy, suggesting that understanding this connection is crucial for solving the problem. Participants encourage further research into kinetic energy concepts to aid in calculations. The conversation highlights the importance of applying physics principles to solve real-world problems.

A 65 kg diver is standing on a diving platform 10.0 m above the water. What is the gravitational potential energy of the diver with respect to the water’s surface?

I know this one,,,
Ep = mgh
e= 65*10* 9.8
= 6370 Joules
or 6.37 kilojoules

If the diver in question 6 falls from the diving platform, what is her speed just as she strikes the water?

but I don't know how to calculate this one...

Use conservation of energy. What's kinetic energy?
 
does speed of the diver have something to do with kinetic energy?

Yes. Perhaps you should look it up.
 
Yep , you were right
 
Can you work it out now?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
