Problem acceleration force vs. gravity

AI Thread Summary
The discussion centers on a physics problem involving a balloon ascending at 15 m/s while a compass is dropped from it after reaching a height of 2 meters. The key challenge is to determine the time it takes for the compass to hit the ground, considering the balloon's constant upward velocity and the downward acceleration due to gravity, which is 9.8 m/s². Participants emphasize the need for a formula that incorporates these factors to solve for the time. The initial conditions of the problem, including the balloon's velocity and height, are crucial for finding the solution. Understanding the interaction between the balloon's motion and gravitational force is essential for solving the problem.

urgent problem acceleration force vs. gravity

Sorry if this is the wrong forum.

I got a problem in my last physics class I am having some trouble with.

A balloon goes straight up with 15m/sec.

After the balloon went up 2m sb. drops a compass.

But the balloon still goes up and doesn't stop.

So the question is when (time) does the compass hit the bottom.

So you probably need to have a equation with the acceleration force of the rising balloon and the gravity (9.8m/square second).

Hope somebody can help me.

Thank you very much.

The way I interpret the question, it is a constant 15 m/s velocity for the balloon.
 

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}...
