How can a body have a velocity east and acceleration west?

AI Thread Summary
A body can have a velocity to the east while experiencing acceleration to the west when it is slowing down in an eastward direction. This occurs because velocity indicates the direction of motion, while acceleration reflects the change in speed. When running east and decelerating, the object maintains eastward velocity but has westward acceleration, resulting in negative acceleration. Understanding that acceleration is the rate of change of speed helps clarify this concept. This scenario exemplifies how acceleration can act in the opposite direction of velocity, leading to a decrease in speed.

Can anyone explain a real scenario in which this would be possible?

Also, I've read about velocity and acceleration, but their differences still seem to confuse me. How can I better distinguish between the two?

You are running east and begin to slow down. Your velocity is still to the east because that is the direction you are going. You are accelerating to the west because your eastward velocity is decreasing.
 
... in other words, in order for an object to change speed, there must be acceleration. If the acceleration was in the same direction as you are running, you would speed up. If the acceleration was at some angle not directly in line with your path of travel, you would veer off course. Lastly, if the acceleration is against you, you will slow down. This is known as negative acceleration (also known as deceleration).
 
The definition of acceleration is the change of speed per time unit. The common equation for linear acceleration is

a = v - v0 / t

where
a - acceleration
v - final speed
v0 - initial speed
t - time

Hope this helps a bit.
 

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}...
