AI Thread Summary
To calculate the forces needed to move and accelerate a trunk weighing 220 N, the static friction force can be determined using the coefficient of static friction (0.41), which results in a maximum static friction force of 90.2 N. To maintain constant velocity, the applied horizontal force must equal the kinetic friction force, calculated with the kinetic friction coefficient (0.32), yielding a force of 70.4 N. If the force applied equals the static friction force used to initiate movement, the trunk will experience an acceleration determined by the net force after overcoming friction. The acceleration can be calculated using Newton's second law, factoring in the weight of the trunk and the applied force. Understanding these forces is crucial for effectively moving the trunk.

Weight of the trunk = 220 N (rests on the floor)
Static friction between the trunk and floor = 0.41
Kinetic friction = 0.32

I want to find the minimum magnitude for horizontal force while I'm starting to push on the trunk. Secondly, what magnitude of the horizontal force must be apply in order to keep the trunk in constant velocity and last but not least, if i continuously to push with the force used to start the motion, what would be the acceleration of the trunk?

Help me on this problem..:shy:

Welcome to PF.

So start with what is the force of static friction?
What is the force of kinetic friction?
 

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}...
