AI Thread Summary
The discussion centers on a request for data related to Newton's Second Law experiment, specifically for calculating acceleration with varying weights. The user missed class and seeks help from others who have completed the lab to obtain necessary data for their calculations. Responses suggest that the user should reach out to their teacher for an extension or assistance in obtaining the data. Additionally, it's emphasized that understanding the calculations and demonstrating work is more important than the data itself. The thread was ultimately locked by a moderator.

Newtons 2nd Law experiment

Homework Statement



I need some data for labexperiment 11 Newtons second law in which you add weights to a hanging weight which pulls a cart through a photogate. Anyway i was wondering if anyone else has done this lab because i need data for the acceleration of the system when the weight has .05 .07 .09 .11 and .13 (kilograms) so i can calculate the force of gravity

Homework Equations



F=MA

The Attempt at a Solution



I know i need to calculate the Force of gravity with the mass of the system however in order ot do so i must know the acceleration which i regretfully do not have.

So what you're asking is has anyone done this lab, so you can copy their data? why didn't you do this is class?

I can't really help you as I never did an actual lab, I instead did it algebraically, acceleration due to gravity (neglecting friction, and on Earth at approx seas level, I forgot the radius) is 9.8m/s.

I guess if you want to say it like that yea i need some data, however data is not important in this labit is the work we show in calculating the force of friction as well as graphs and I was not in the classs to get the data i was on a family trip and came back as we got out of school for a week and a half winter break.
 


ask your teacher over the email for an extension or ask a friend

or if you have no friends (kidding :) ) then email your teacher and ask for numbers.
 


I agree, explain to your teacher that you were away with your family and ask how you can (properly) obtain the data you need to complete the assignment.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
