Seems the both of us haven't done the project yet.
According to the definition of the force, It is defined as <u>the multiplication of the mass and acceleration</u> (or, the rate change of the quantity of motion)
![F=ma](https://tex.z-dn.net/?f=F%3Dma)
where:
- F: is the force in Newtons (N)
- m: is the mass in kilograms (Kg)
- a: is the acceleration in ![m/s^{2}](https://tex.z-dn.net/?f=m%2Fs%5E%7B2%7D)
Then, in our problem
![F=ma= 500 * 15=7500 N](https://tex.z-dn.net/?f=F%3Dma%3D%20500%20%2A%2015%3D7500%20N)
