AI Thread Summary
The discussion centers on calculating centripetal acceleration and the forces involved for a car rounding a curve. The user initially calculated the centripetal acceleration as 0.66 m/s² but is confused about the force maintaining this acceleration, providing several different answers. A participant points out a typo in the user's equation, clarifying that it should be ma = mv²/R. They also request the user to share their calculations for better assistance. The conversation emphasizes the importance of accurate equations in solving physics problems.

just need to know what to do i keep getting different answers


[SFHS99 7.P.44.] A 13750 N car traveling at 47.0 km/h rounds a curve of radius 2.60 102 m.

(a) Find the centripetal acceleration of the car.


.66 m/s sqaured


(b) Find the force that maintains centripetal acceleration.
<this is what i can't get right here is what i got please tell me what to do>

N

9014.18

9006.38

1403.06

those are the answers i got can someone please tell me the right answer and how to get it that's a lot and equation would be nice i have been using

ma = ma(v^2)/R

(c) Find the minimum coefficient of static friction between the tires and the road that will allow the car to round the curve safely

.067 = coef.


thanks

The equation you're using has a typo.
It's supposed to be ma = mv2 / R (without that extra a).

a) I got a different answer (R = 102m, if I understood the numbers right?)
b) and c) Could you show what you've tried, and why?

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
