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?

For the below questions, consider a consumer that consumes two goods, x and z with the following utility function. u with bar on top space equals space x to the power of 1 third end exponent z to the power of 2 over 3 end exponent suppose initial values for income and the prices of goods x and z are y equals 90, p subscript x equals space 10, and p subscript z equals 15 respectively, then the price of good x falls to syntax error from line 1 column 89 to line 1 column 100. unexpected '\'.. what is the magnitude of the total effect
