Faster or Slower: Doubled Mass & Wall Slide

  • Thread starter Thread starter pyroknife
  • Start date Start date
AI Thread Summary
The discussion centers on whether doubling the mass of an object affects its sliding speed down a wall. The original poster initially believed that increased mass would lead to faster sliding but later realized that greater mass also results in increased friction, potentially slowing it down. Participants emphasize the importance of understanding the forces at play, including normal force and friction, and question whether the problem specifies ignoring air resistance and friction. Clarification is sought regarding the exact problem statement, particularly if it involves a vertical wall or an inclined plane. The conclusion suggests that the acceleration due to gravity and friction's role may lead to mass independence in certain scenarios.

THeres this question on my homework that asks if the mass was doubled would the object slide down the wall faster than the original mass. I said yes it would, but then I caluculated the friction of both and the doubled mass has a larger friction wouldn't that make it slower?

What is the full problem statement?

Does it say to ignore air resistance, friction, etc...?
 
Is the wall perpendicular to a flat ground? If so, think about what would happen if you dropped an object against the wall; for there to be a force of friction there must be a normal force on the object from the wall, and if there is a normal force against the object perpendicular to its motion, the object will either accelerate away from the wall for the brief instant the object is in contact with the wall, or else there must be some other force keeping the object pushed up against the wall. Does this other force exist?
 
I feel that the OP meant a mass sliding down an inclined plane, in which case the force along the plane is ma = mgsin(theta) – kmgcos(theta), and so the accn is independent of the mass. This applies to the vertical wall as well. But of course only the OP can give us the actual problem.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

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}...
