AI Thread Summary
The discussion clarifies that 1.25 m/s² is an acceleration, not a velocity, which is crucial for solving the problem of how long it takes to travel 15 meters. Participants emphasize the need to convert acceleration into velocity to calculate the time required for the distance. The conversation highlights the importance of understanding the distinction between acceleration and speed in physics problems. Ultimately, the correct approach involves applying kinematic equations to derive the time from the given acceleration. Understanding these concepts is essential for accurately solving motion-related problems.

For example if an object moves at 1.25 m/s^2, then how long will it take to move 15 meters?

Did you mean that to be an acceleration or a speed (in m/s)?

What do you think?
 
Thank You now I understand you got to convert acceleration to velocity in order to answer this example.:):):)
 
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}...
