A condition which would always result in a net force of zero (0) Newton is: A. Two equal but opposite forces act on an object.

Newton's Second Law of Motion states that the acceleration of an object is inversely proportional to its mass and directly proportional to the net force acting on the physical object.

Mathematically, Newton's Second Law of Motion is given by this formula;

$Acceleration = \frac{Net \; force}{Mass}$

According to Newton's Second Law of Motion, the acceleration of a physical object occurs when there is a net force on an object while a net force (sum of all the forces) zero (0) causes no acceleration.

In Science, an object is said to be at equilibrium when two equal but opposite forces are acting on it and this would always result in a net force of zero (0) Newton.

<u>For example:</u>

$0 N = 5N + (-5N)\\\\0N = 5N - 5N$

Hey there!

Seems like you're looking for the size and direction to the final velocity of the two cars. To find it, you must solve it like this.

0.4 kg(3 m/s) + 0.8kg(–2 m/s) = 1.2 kg m/s -1.6 kg m/s = –0.4 kg m/s

–0.4 kg m/s = 1.2 kg(v) = (–0.4 kg m/s)/(1.2 kg) = v = –0.33 m/s

So, the cars are traveling at -0.33 m/s in the direction of the second car.

Hope this helps

Suppose the carts collided on a surface that had a slight incline to it. Would you expect the momentum to be conserved

lesantik [10]

Momentum is conserved when carts are collided on a slanting plane.

To find the answer, we need to know about the conversation of momentum.

<h3>What's the conversation of momentum?</h3>

Conservation of linear momentum says the total momentum before the collision and after the collision remains the same.
Mathematically, m1u1+m2u2 = m1v1+m2v2

<h3>How is the momentum conserved when collision occurs on a slanting plane?</h3>

On a slanting plane, the velocity has two components,

horizontal component
horizontal component Vertical component

So, its momentum has also similar two components.
The momentum is conserved along horizontal direction and vertical direction separately.

Thus, we can conclude that the momentum is conserved when carts are collided on a slanting plane.
