Question

An aircraft weighing 994 N is accelerated at 11 m/s/s for 11 seconds, at which time the aircraft launches. How much work was done on the aircraft? The acceleration is constant.
Hint: This is a multiple step problem in which you must derive the variables needed (mass and distance under constant acceleration) in step one and then apply those values to the final solution of the problem in step two, that is calculate the work done.

Explanation / Answer

W=Fx

=max

=994/9.81 * 11* (0.5*11*11^2)

=741.75 kJ
