. What must be the thrust on each of its four engines? What is the horizontal force that a 700 N pilot exerts on his seat? can someone help me to solve this? :laughing: :laughing: :D Title: Re: A 40 tonne jumbo jet accelerates down the runway at 5 m/s2 .

where;f=force,m=mass and a=acceleration m=40 tonne x (1000 kg)/(1 tonne) m=40,000 kg F=40,000 kg*5 m/s^2 F=200,000 kg m/s^2 =200,000 N=200 kN the thrust on each of its four engines Fs= force of the seat on the pilot Fg= gravitational force ∑FNet = Fs+Fg Since FG is downward acceleration, therefore, ∑FNet = Fs+Fg Fs=200,000 N+700 N Fs=200,700 N All the best.
