Find the value of F1 + F2 + F3.

F = 0.78[N]

Explanation:

The given values correspond to forces, we must remember or take into account that the forces are vector quantities, that is, they have magnitude and direction. Since we have two X-Y coordinate axes (two-dimensional), we are going to decompose each of the forces into the X & y components.

For F₁

For F₂

For F₃

Now we can sum each one of the forces in the given axes:

Now using the Pythagorean theorem we can find the total force.

according to the law of conservation of momentum, the momentum of the object after the collision is
