Accleration Final Initial Speed

AI Thread Summary

To calculate distance given acceleration, initial speed, and final speed, the correct equation is v^2 = u^2 + 2as, where v is the final speed, u is the initial speed, a is acceleration, and s is displacement. It is important to rearrange the equation to solve for s. In scenarios involving deceleration, the acceleration value should be negative, such as -2.68 m/s². This approach ensures accurate distance calculation in motion problems. Understanding these principles is crucial for solving related physics questions effectively.

Seannation

The equation you've used is finding time, not distance.

The equation to use in this case is:

v^2 = u^2 + 2as

Where v is the final speed, u is the initial speed, a is the acceleration and s is the displacement.

Rearrange this to find s.

Remember that the driver is decelerating, so the acceleration is -2.68 ms^-2.

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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}...

Thread 'Understanding Forces and their Vector Components'

I was told forces are vectors so they can be divided into x and y components, but what about the normal force or the force of static friction? do you divide those into x and y components if say you had a block that was lying on an angled surface?
