    Brakes Car Work
AI Thread Summary
To determine the work done in stopping the car before it falls off the cliff, key variables such as the initial velocity and the friction of the road are essential. The car's weight is 5710 N, and it decelerates at 9.94 m/s². The work-kinetic energy theorem is applicable, but without the initial velocity or time to stop, calculations cannot proceed. Additionally, the problem involves both scalar and vector components, which need clarification. Accurate information on these factors is crucial for solving the problem effectively.

A car and driver weighing 5710 N passes a sign station (bridge out in 23.1 m) She slams on her brakes and the car decelerates at a constant rate of 9.94 m/s^2. Accel of grav is 9.8 m/s^2. What is the ganitude of work done, stopping the car before it falls.

We don't know how to do it at all =/ help please!

HELP! its due at 11 TONIGHT =)
 
I'm not sure how to answer your question, but if you read the forum rules, you need an attempt of some sort before you get any help. Most certainly, they will not do the question for you.

Looks like you're out of luck.
 
you have to know the friction of the road as well as the initial velocity in order to find out, then you would use the work-kinetic energy theorem.
 
You would also need to know the initial velocity and or the time that it takes for the car to stop, also, you were also talking in two components, and work is a scalar, and you didn't specify in what component. So yeah…

Sorry, cannot help you there.
 
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}...
