AI Thread Summary
The problem involves calculating the average force exerted by a stone weighing 20N that falls from a height of 5m and compresses 5 cm upon impact. The equation used is mgh = F * delta l, where m is the mass, g is the acceleration due to gravity, and h is the height. The calculated average force is F = (20 * 9.81 * 5) / 5, resulting in 196.2N. The solution appears to be correct based on the provided calculations. This method effectively determines the average force of impact.

The Attempt at a Solution



is this correct way to solve it

mgh=F*delta l

F=mgh/delta l=(20*9.81*5)/5 =196.2N

correct ?

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}...
