AI Thread Summary
Tension affects friction and acceleration by determining whether a mass will move on a horizontal surface. If the tension exceeds the kinetic friction force, the mass will accelerate. The normal force (N) equals the weight of the mass (Mg) on a level surface. If the mass does not accelerate, the tension must be less than or equal to the static friction force. Understanding these relationships is crucial for solving related physics problems.

Homework Statement


What concepts am I missing?


A mass M is initially at rest on a horizontal surface, ms=0.30 and mk=0.20 . A horizontal string then pulls M with a tension T. Forces below are magnitudes.

Correct Incorrect M will accelerate if T exceeds ukN
Correct Incorrect N equals Mg
Correct Incorrect M will accelerate if T exceed usN
Correct Incorrect T equals usN if M remains at rest
Correct Incorrect If M does not accelerate, then T less than or equal to usN
Correct Incorrect The NET force on M (if M does not move) is ukN


Homework Equations





The Attempt at a Solution



correct by exceeding the kinetice friction the mass will accelerate
correct N and mg cancel on a level surface
correct it will move from rest
incorrect it could be lower than usN
correct
incorrect it would be true for ukn

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}...
