Finding coefficient of friction and angle of incline

AI Thread Summary
To find the coefficient of friction and the angle of an incline using a distance of 18.0 meters and a time of 10.0 seconds, one must first determine the acceleration. Participants suggest using kinematic equations and Newton's second law, emphasizing the importance of understanding free body diagrams. The discussion highlights that assumptions may be necessary, such as estimating weight to calculate forces. One user confirms that they figured out acceleration and used a weight of 10 kg to solve for forces. Overall, the conversation encourages learning the underlying principles rather than simply seeking a solution.

I need to find the coefficient of friction and the angle of an incline with only knowing a distance of 18.0 meters and a time of 10.0 seconds. I have absolutely no idea where to begin because my teacher never taught us how to do such equations. if anyone can figure the problem out for me that would be awesome of you. thanks a lot!

Is this exactly how the problem was given to you?

Perhaps the point is to have you go learn it yourself. Do you have a textbook?

No one here will just hand you a solution, but we will help you. Do you know how to draw a free body diagram? Do you know Newton's second law? Kinematics equations? What have you learned so far?
 
I have the same problem, but just with different numbers, mine being 12.0m and 8.00s.

My question is whether or not I have to find acceleration.

Also, should I be assuming for one and then solving for the other? I mean, we are given no other forces so they must not have any importance.

Nevermind, got it. Acceleration is just m/s and then you just use any weight (I used 10 kg) in order to figure out the forces, which are variables.

nothingknower did you just assume for the angle?
 

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}...
