AS Level Physics questionWatch
Draw a free body diagram and turn the thrust into its vertical and horizontal components. Figure out the weight of the helicopter (although I thought that would have been the 19kN, maybe I've misunderstood the question?) then the mass. Label the vertical thrust and use trig to work out the horizontal force of the thrust. Then u should know an equation to figure out the acceleration
Then I did 19.29... x sin(10)=3.35.... kN
F/M=A 3350.2..../1900kg (assuming this is the mass)=1.76ms-2
But the answer in the book is 1.73 ms-2 which confused me.
