Not sure where to start with this question? Constant force must mean that the acceleration is constant right? So does this mean that I can use the SUVAT equations in my calculations?A glider of mass 200kg needs to travel at 50 m/s before it can take off. It starts from rest and a constant force of 500N pulls it along. If air resistance is $\displaystyle 10v$ N, where $\displaystyle v$ is the speed of the glider, how long does the glider take to get air born?

If the runway needs to be at least 200 m longer than the required take of distance, what should it's minimum length be?

Thank in advance for any pointers
