    Force Resultant
AI Thread Summary
When the 1000N force acting to the left is removed from the packing crate, the remaining forces are 300N to the right and the friction force. Since the crate is at rest, the friction force must balance the applied forces, which means it would adjust to 300N to the left to counteract the 300N force to the right. Therefore, the resultant force acting on the crate is zero. The reasoning presented confirms that the friction force compensates for the rightward force, leading to no net movement.

Homework Statement


A packing crate rests on a horizontal surface. It is acted on by three horizontal forces: 1000N to the left, 300N to the right, and friction. The weight of the crate is 500N. If the 1000N force is removed, the resultant force acting on the block is

A) zero
B) 300 N to the left
C) 300 N to the right
D) 500 N to the left
E) impossible to determine from the information given.


The Attempt at a Solution



I would say E) since I have no info about the friction. Could you please confirm.

Thank you

It's not brilliantly worded, but I think the clue is when it says that the 'crate *rests* on a horizontal surface'. i.e. it isn't moving. That should give you some info about the friction force.
 
Alright so when the crate is resting the friction would be 700.

If we remove the 1000 N force, the friction would be to the opposite direction and decrease to 300 to cancel the right force.

The resultant force would A) zero.

Is there any problem in this reasoning.
 
Looks fine to me!
 

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}...
