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?Quote:

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 N, where 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
