How Do You Calculate the Speed of a Ball Returning to the Bottom of an Incline?

AI Thread Summary
To calculate the speed of a ball returning to the bottom of an incline, first determine the acceleration of the ball as it rolls up the incline. The friction coefficient between the ball and the incline can also be calculated. Using the law of conservation of energy allows for finding the final speed when the ball returns to the bottom. This approach considers the potential energy at the highest point and the kinetic energy at the bottom. Understanding these principles is essential for accurate calculations.

when a ball is rolled up an incline plane,the incline degree,the distance that it goes are given.the time that it require to reach the highest point is also given.but,how to find the speed when it gets back to the bottom??

pls help
thanx

You can find the acceleration of the ball when it rolled up the inclined plane. Then you can find the friction coefficient between the plane and the ball.

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}...

Thread 'Struggle to understand the concept of the 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...
