How Do You Calculate the Coefficient of Friction on an Inclined Slide?

AI Thread Summary
To calculate the coefficient of friction on an inclined slide, it's important to recognize that Matthew's constant speed indicates zero acceleration. The normal reaction force between Matthew and the slide is calculated as 311N. The equations of motion indicate that the frictional force equals the component of gravitational force acting down the slide. By equating the frictional force to the normal force multiplied by the coefficient of friction, one can solve for the coefficient. Understanding these relationships is crucial for solving the problem accurately.

Homework Statement



1. A childs slide is straight and inclined at 25o to the horizontal. Matthew of mass 35kg goes down the slide at a constant speed.

(a) draw a diagram
(b) find the magintude of normal reaction force between matt and slide.
(c) Find the coefficient of friction between matt and the slide

part (a) and (b) are fine i got 311N for part (b) but couldn't find (c)


Homework Equations



F = MA
F = ,U (mew) x R


The Attempt at a Solution



Resolved it in direction of friction got;

Fr - 35gsin25 = 35a
could not do this as had two unknowns
same with
F = mew x 311 and F = 35a

any help would be greatly appreciated!

Matthew of mass 35kg goes down the slide at a constant speed.

What does that imply about the value of the acceleration?
 
it implies that the acceleration is zero, i see now, thanks very much for your help :)
 

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}...
