Finding Initial Velocity to Equations

AI Thread Summary
To find the initial velocity of an object, the appropriate equations depend on the known variables. Key equations include V = Vi + at, s = ut + 0.5at^2, and v^2 = u^2 + 2as. There is no single equation for calculating initial velocity; instead, it requires working backward from final conditions if needed. The choice of equation is contingent upon the information available. Understanding the context of the problem is essential for determining the correct approach.

What equation do I use to find the initial velocity of an object?
 
Physics news on Phys.org
You can use Velocity = Initial Velocity + Acceleration*Time

V=Vi + at
 
Or s = ut + 0.5at^2

or v^2 = u^2 + 2as

it depends on what you know already.
 
There is no equation "to find the initial velocity of an object".
 
Sorry -- that was a bit hasty. I guess there could be a problem that gave you final conditions and asked you to work backward to the initial conditions. As tyco05 said the equations you would use to do that would depend on what you already know so there is no equation in general "to find the initial velocity of an object".

Thank you!
 

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}...
