Circular Acceleration Car rounding turn wrong statement

AI Thread Summary
The statement "The car rounds the turn at a constant velocity of 50 km/h" is incorrect because a car turning is undergoing circular motion, which involves a change in direction, thus implying acceleration. The correct terminology should focus on constant speed rather than constant velocity. A suitable rewrite would be "A car rounds a turn at a constant speed of 50 km/h." This distinction is important as it aligns with Newton's First Law, which states that an object in motion will remain in motion in a straight line unless acted upon by an external force. Understanding these concepts is crucial in physics discussions about motion.

Homework Statement



What is wrong with the physics in the following statement? “The car rounds the turn at a
constant velocity of 50 km/h.” Rewrite it so that it conveys the correct meaning.

Homework Equations



none

The Attempt at a Solution



I'm thinking it's something to do with Circular motion, should it be Constant Acceleration?

Newton's First law would imply that an object moving at constant velocity would move in a straight line.
 
ok, that makes sense, so I would rewrite it to: A Car rounds a turn at a Constant Speed of 50 Km/hr? Would that be a good re-write?

Yes, that would make more sense.
 
Cool thanks for your help.

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}...
