A jet engine develops 1 * 10^5 n of thrust in moving the airplane forward at a speed of 900 km/h. What is the power developed by the engine? I thought I needed to convert 900 km/h to m/s, so I did and I got 15000 m/s. The only equation I see to use for this is: P = Fvcosθ When I used the equation, I got: P = Fv = (1*105)(15000 m/s) = 1.5 * 109 I know I went wrong somewhere because it is multiple choice and that wasn't any of the answers. Please help me see my error(s) and help me get it right. I need this done a.s.a.p. by tomorrow. Thanks.
