A Solid Cylinder rolling down a ramp

AI Thread Summary
A solid cylinder rolling down a ramp without slipping will experience changes in its motion if the surface becomes slippery. The equations of motion indicate that potential energy converts to kinetic energy, with friction playing a crucial role in this process. As friction decreases due to a slippery surface, the cylinder's acceleration may be affected, leading to uncertainty about whether it will roll faster or slower. The discussion emphasizes the relationship between friction, force, and the cylinder's speed. Ultimately, the reduction in friction suggests the cylinder could potentially roll faster down the ramp.

1.A solid cylinder rolling down a ramp without slipping.

if the surface were slippery, would the time increase or dcrease.



2. PE+KE = PE +KE
mgh = 1/2IW^2+1/2mv^2
F=ma
f= mgsin(theta)/(1+mR^2/Icm)


3. Apperantly this question has several parts. The previous ones were related to the equations on top. This should also relate to the force, since the friction of the ramp will decrease due the the rain. I am really not sure how to start this problem. @_@

Since the friction decreases, do you think the cylinder will be going faster or slower?
 

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}...
