AI Thread Summary

To isolate the equation for time, the equation d = V1(t) - 0.5(a)(t^2) can be rearranged to form a quadratic equation in t. The rearranged form is d - 0.5(a)(t^2) = V1(t), which leads to a standard quadratic equation. This equation can be solved using the quadratic formula, yielding two potential solutions for t. The discussion emphasizes the importance of recognizing the equation's quadratic nature to find the correct time values. Understanding this process is crucial for solving similar physics problems involving motion.

Homework Statement

I am having trouble isolating this equations for time

d= V₁(t) - 0.5 (a) (t²)
2. The attempt at a solution

I get this:

d-0.5(a)(t²) = t
that is all over V₁

that's a quadratic equation in t;
it has two solutions for t , given by the "quadratic formula".

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?
