AI Thread Summary
The problem involves a ball thrown to a height of 10 meters and then caught back at the starting point. The displacement is calculated as the difference between the initial and final positions. Since the ball returns to the original position, the displacement is zero. Therefore, the answer is that the displacement of the ball is 0 meters. This conclusion highlights the importance of understanding displacement as a vector quantity that considers initial and final positions.

A ball was thrown up to a height of 10m and catches it back.what is the displacement of the ball
 
Physics news on Phys.org
Displacement = InitialPosition - FinalPosition
 
Please could u solve it and post here?plss
 
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}...
