    Force Power
AI Thread Summary
The discussion centers on understanding the relationship between power and force in the context of a cyclist's performance. A cyclist is moving at 8 m/s with a power output of 500W, and the main inquiry is about calculating the force exerted on the pedals. Clarification is provided that the force required to propel the bike forward may differ from the force applied to the pedals. The conversation emphasizes the importance of distinguishing between these two forces when solving the problem. Understanding this distinction is crucial for accurately applying physics concepts to real-world scenarios.

Hi
just took my physics test today and it turns out that the 2 problems i couldn't get both happened to test my understanding of the relation between power and force. I don't have numbers but i'd like to get a better understanding of that concept so.. here's the gist of it:

There's a cyclist moving at 8 m/s w/ 500W. Find the force used to push down the pedal.

something like that. Any little hint would be appreciated! Thanks

something like that.

Are you sure that the problem asked for the force used to push down the pedal? The reason I ask is that the given information is sufficient to tell you the force with which the bike is propelled forward, but that is not necessarily the same as the force applied to the pedal.
 
if not the force applied to the pedal, then it's probably the force that propels the bike forward.

*I don't remember the exact wording, but i;m sure of the info that was given.
 
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}...
