Newton law Applications. Any suggestion

AI Thread Summary
To determine how far mass M will travel after being set in motion, the work-energy theorem can be applied, or alternatively, Newton's second law can be used to find the acceleration. The coefficients of static and kinetic friction (Us and Uk) will influence the deceleration of the mass. The initial speed (Vo) and the gravitational force (w = -mg) are also critical in calculating the distance traveled. The discussion emphasizes the importance of understanding these fundamental physics concepts to solve the problem effectively. Overall, applying these principles will yield the distance M travels before coming to a stop.

A mass M at To =0 s has a speed of lVol in the positive X direction. The floor has a coefficient of static friction of Us and a coefficient of kinetic friction of Uk. How far will the mass M travel?

mass = M
@ To = 0s
speed = Vo
coefficient of static friction = Us
coefficient of Kinetic friction = Uk

w=-mg
a=?

I don't really know how to start to my problem.
any hint?

Thanks!

hi tubspring! welcome to pf!

(have a mu: µ and try using the X2 icon just above the Reply box :wink:)

use the work-energy theorem :smile:​

(if you don't know that, then use good ol' Newton's second law to find the acceleration, then use the standard constant acceleration equations)
 
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 hanged mass'

Thread 'A cylinder connected to a hanged 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...
