The formula F=ma will give you the answer to your physics question. F is for force, measured in Newtons or N, m is for mass, measured in kilograms or kg, and a is for acceleration, measured in meters per second squared, or m/s^2. To solve this equation, use 15,000 kg for m and 1 m/s^2 for a and multiply them together to get your force. You should get 15,000 N (newtons) as your answer. Also, if the question asks for mass or acceleration, all you have to do is change the equation of F=ma around so that if you need to solve for mass, the equation would be m=F/a and if you need to solve for acceleration, the equation would be a=F/m.
Although this does not pertain to your question, depending on how in-depth your physics class gets you may see problems dealing with gravity or g. Keep it mind that gravity accelerates at a speed of 9.81 or 9.8 m/s^2 as Newton discovered. So if you come across a physics question dealing with gravity or g, always use 9.8 or 9.81 (to be exact) as the number for g.

F=ma, so:
15,000N I think
