1/4. i believe but im not too sure
1. To solve for a you need to take out any variable that is with it. F=ma, so divide by m on both sides to get F/m=a.
2. Use the previous formula/equation for this. Plug in the numbers, so -25/10=-2.5 units.
3. You're looking for the mass, so you do the same thing to the previous formula. F=ma, so divide F by a to bring it to one side, isolating m. F/a=m, plug in numbers, 25/5=5 units.
