Calculating Force Components and Impact Force for Flight Recorder Testing

AI Thread Summary
To calculate the components of a force vector with a magnitude of 671 N at an angle of 65.8° north of east, trigonometric functions sine and cosine are used to find the north-south and east-west components. For the impact force on a flight recorder, a 45-kg box thrown at 210 m/s and stopped in 5.7 ms requires applying impulse and momentum principles to determine the average net force. The formula used is \overline{F} = m\frac{\Delta v}{\Delta t}, where the change in velocity and time of collision are critical. Users are encouraged to share their calculations for verification if they encounter discrepancies in their results. Accurate application of these formulas is essential for proper analysis in both scenarios.

Need help With This...

i don't know which formulas to use to find the answer..please help...thanks in advance...

1.A force vector has a magnitude of 671 N and a direction of 65.8° north of east. Determine the magnitude of the components of the force that (a) point along the north-south line and (b) along the east-west line.

2.Airplane flight recorders must be able to survive catastrophic crashes. Therefore, they are typically encased in crash-resistant steel or titanium boxes that are subjected to rigorous testing. One of the tests is an impact shock test, in which the box must survive being thrown at high speeds against a barrier. A 45-kg box is thrown at a speed of 210 m/s and is brought to a halt in a collision that lasts for a time of 5.7 ms. What is the magnitude of the average net force that acts on the box during the collision?

1. The force vector and its two axile components form a right triangle with an angle of 65.8°. Use the trigonometric functions sine and cosine to find the magnitudes of the axile components.

2. Using impluse and momentum:
\overline{F}\Delta t = m\Delta v
\overline{F} = m\frac{\Delta v}{\Delta t}
If you don't know about these, you can get to the same answer from Newton's law:
\overline{F} = ma = m\frac{\Delta v}{\Delta t}

hey thanks for the help...i really appreciate it..but for some reason i used what you said and i got the answer wrong...i don't know where i did wrong..can someone double check for me..thanksssssssssssss
 
Which question? And can you please show me what you did, so I can correct your methods if need be.
 
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}...
