What is the maximum height a block will rise when the force is removed?

    Block Spring
AI Thread Summary
To determine the maximum height a 0.2kg block will rise after the removal of an external force compressing a spring with a spring constant of 100N/m, the initial compression of the spring must be known. The block's weight contributes to the spring's compression, but without the specific value of the external force or additional compression, the problem cannot be solved numerically. Participants in the discussion express difficulty in proceeding without these key details, suggesting that a symbolic solution involving the force or compression distance may be necessary. The conversation highlights the importance of understanding the relationship between force, spring compression, and gravitational potential energy. Ultimately, the lack of complete information prevents a definitive answer from being reached.

I have tried all sorts of ways to solve this problem, but it has gotten the better of me.
A 0.2kg block is held in place by a force F that results in the compression of a spring beneath the block. The spring constant is 100N/m. Assuming the mass of the spring is negligible compared to that of the block to what maximum height would the block rise if the force F were removed.

Any and all help would be appreciated.

The block exerts a downward force on the spring (its weight), which compresses it. But an additional force compresses the spring more. Without any more info, (the force or added compression), I don't know how to solve it...
 
that's where I got stuck too. I found the accelration for the force on the spring but I don't know where to go from there.
 
Maybe the expected answer is a symbolic one with F or D included as a variable, rather than an actual number.
 

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}...
