The acceleration of the car will
The mass of the car will
The velocity of the car will

Nov 20, 2014 - In the second part of the activity, mass is added to the toy car to illustrate Newton's Second Law. ... If the object is in motion, the force changes its velocity. ... on an object is equal to the mass of the object times its acceleration.

Step-by-step explanation: think of newtons first law and start from there and you should get it on your first thought on your problem.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
