Kinetic Energy: What am I doing wrong?

AI Thread Summary
The discussion revolves around calculating the kinetic energy of a car with a mass of 1880 kg traveling at 14.7 m/s. The correct formula for kinetic energy is applied, which is 1/2mv^2. Initial calculations were incorrect due to using the wrong mass, but after correcting to 1880 kg, the resulting kinetic energy is 203124.6 J. The user initially faced issues with submission, realizing they were entering the answer in the wrong field. The conversation highlights the importance of accuracy in both calculations and submission processes.

Homework Statement


A (n) 1880 kg car travels at a speed of 14.7 m/s. What is it's kinetic energy? Answer in units of J.

Homework Equations



Kinetic energy= 1/2mv^2

The Attempt at a Solution


1/2(188)(14.7)^2= 20312.46
My answer is wrong though...
What did i do? I keep getting all the kinetic problems i have wrong and i am following the formula...
 
Physics news on Phys.org
It's supposed to be 1880 kg, you used 188 kg.
 
Ok so now i did .5(1880)(14.7)^2 = 203124.6
It's still wrong...
 
Why do you say its wrong? Is the answer your comparing it two 203000? or even 200000? It could be sig figs.
 
Ahh i figured it out. I was submitting it in the wrong blank.
 

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...
