How do you find average value of normal acceleration?

AI Thread Summary
To find the average value of normal acceleration, the correct approach involves calculating the normal component of linear acceleration rather than angular acceleration. The discussion highlights a misunderstanding where one participant initially calculated angular acceleration instead of focusing on linear acceleration. To compute the normal component accurately, it is suggested to consider the direction between the two velocities involved. The conversation emphasizes the need for clarity in distinguishing between different types of acceleration. Understanding these distinctions is crucial for solving the problem correctly.

Homework Statement



Find average value of Normal Acceleration from the information given. (See the picture)

Homework Equations



a^{→}_{ave}= Δv^{→}/Δt

a_{t}=Δv/Δt


The Attempt at a Solution



I took the difference of the given angles in radians and divided it twice by Δt and get 3.6 rad/s^{2} but the answer was wrong as expected. Please help.

hi gikiian! :smile:

no, rad/s2 is angular acceleration, isn't it?

you need the normal component of the ordinary (linear) acceleration :wink:
 
Hey tiny-tim!

I have successfully obtained the linear acceleration vector. Would you now like to tell me with respect to what entity should I compute the normal component of it?

my inclination would be to use the direction halfway between the two velocities
 
You can'y do that.
 

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}...
