How Does Mass Affect Acceleration on a Frictionless Surface?

AI Thread Summary
The discussion revolves around determining the acceleration of an object on a frictionless surface when a force F0 is applied. The initial condition states that the object accelerates at 20 m/s², but the user is confused about how to solve the problem without knowing the mass. A helpful suggestion is made to treat the mass as a variable 'm' and proceed with the calculations, noting that the mass will cancel out in the final equations. This approach allows for the determination of acceleration regardless of the specific mass value. The conversation emphasizes the importance of understanding the relationship between force, mass, and acceleration in physics.

Hi a18c18! Welcome to PF! :smile:

Hint: Just call the mass m, and do all the equations as usual …

you'll find that you can cancel the m's in the end! :smile:
 
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}...
