Homework Statement The difference between cinematique and dynamique physics For example: *THIS IS WRONG* cinematique is the reason why objects move and dynamique is how the objects move. I don't know what the real answer is Homework Equations None needed The Attempt at a...

and for the cable holding the car force of gravity 4500(9.8) = 44100 F net = 4500*1.4 = 6300 44100+6300 = 50400N

okay so first i add the two weights 15000 + 4500 = 19500kg force of gravity fg=mg = (19500)(9.8) = 191100 force net F=ma = (19500)(1.4) = 27300 Newtons So the force that the blades need to put out in order to lift the helicopter and the car at a acceleration of 1.4m/s^2 is 27300+191100...

So the angle is 18.1 degrees? Correct?

That was my attempt to draw the free body diagram of the problem it didnt work out someone please help what he said was close to jibberish to me

So for problem two, (40N) / __________ / (3N) | |/ ) <--- Angle X <-------| 10kg |---------- L_________| Net force = 3.5*10 = 35N Now i am stuck?!?

so is it moving towards the north or the south and what exactly is the acceleration?

Problem 2 is my biggest problem i have no clue at all how to get that angle someone please help

if its moving towards the south how is it possible that the resulting force is towards the north?

bump update

f=ma ( i go to a french school its kinda hard to translate )
