An engineer wants a 4000kg helicopter to fly horizontally (neither gaining nor losing altitude) and increase speed at a rate of 2.6m/s2 despite experiencing a 1000N drag. How many forces are acting on the helicopter?
Are all the forces on the helicopter balanced?
What is the magnitude of the net force on the helicopter?
What is the strength of the horizontal thrust component?
What is the strength of the thrust?
At what angle, θ, does the helicopter need to tilt?

i believe it is b. what was the cause of the big bang

hope this !

1/0.14nm = 10^10/1.4 a lot

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
