    Displacement
AI Thread Summary
To calculate displacement, additional information such as time and acceleration is necessary. The formulas for displacement include s = ut + (1/2)at² and v² = u² + 2as, where s is displacement, u is initial velocity, t is time, and a is acceleration. Given the initial velocity of 0 and a final velocity of -2, the displacement is likely negative, indicating movement in the opposite direction. Without knowing the acceleration or time, an accurate displacement cannot be determined. Thus, more data is required to solve the problem effectively.

okay i have a question.
if a squirrel is at 0 on inital velocity and then is at -2 at final velocity.then what is its displacement?
And i would appreciate it if someone can tell me the fourmla for displacement.:smile:
 
Physics news on Phys.org
you need to give a lot more info to be able to do this problem

disp= x_o+v_0*t+1/2at^2
 


I think you would have a negative displacement you instead of going forwards went backwards your displacement would be 2. I think I have problems with physics so...
 


Like mathmike said, you need to give a lot more information so an accurate displacement can be given, unless you are searching for displacement as a function of acceleration/time etc.

Using:

s=ut+\frac{1}{2}at^{2} (1)

or

v^{2}=u^{2}+2as
Hence, s=\frac{v^{2}-u^{2}}{2a} (2)

where,
s=displacement
u=initial velocity
t=time
a=acceleration

Using the information you have given, formula (1) can be simplified to:

s=\frac{1}{2}at^{2}

and formula (2) can be simplified to:

s=\frac{2}{a}

It is obvious you will at least need acceleration to find the displacement, and yes, the displacement will be negative since your final velocity (v) is negative.
 
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}...
