How far does the jet travel during the 9 s?

Hello Guest!

$$a=\frac{F}{m}\\ s=\frac{a}{2}t^2\\ \color{black}s=\frac{F}{2m}\cdot t^2=\frac{60900N}{2\cdot 4375kg}\cdot 9^2\cdot s^2\cdot \frac{kg\cdot m}{N\cdot s^2}$$

$$s=563.8m$$

From a standing start and without taking air resistance into account, the jet travels 563.8 m.
