Temperature increase in water question

AI Thread Summary
A 50kg aluminum block is dropped from a height and strikes water at 150m/s, converting its kinetic energy into heat. The kinetic energy calculated is 562,500 Joules. This energy is used to heat 5kg of water, leading to a temperature increase of approximately 26.9 degrees Celsius. The discussion emphasizes the importance of using correct units and understanding the kinetic energy equation. Overall, the calculations demonstrate the relationship between kinetic energy and temperature change in water.

1. A 50kg alumium block is dropped from a large height and hits a container of water at 150m/s. Assuming all the kinetic energy of the falling block goes into heating the 5kg water, what is the temperature increase of the water.

Homework Equations


Q=mc(change of t)
KE=.5m(v^) maybe?[/B]

The Attempt at a Solution



.5(50)(150^)=562500 Jules
562500= 5(4180)(change of t)
change of t= 26.9[/B]

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 '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...
