A compressed spring is compressed between a 5kg and 3 kg cart, respectively. When the spring is released, what will be the same

stira [4]

The momentum of the two carts will be the same

Explanation:

First of all, we notice that the system consisting of the two carts + the spring is an isolated system: this means that there are no external forces acting on it.

As a result, the total momentum of the system must be conserved.

Since the spring is at rest, the total momentum of the system after the two carts are released is:

$p_f = p_1 + p_2$

where

$p_1$ is the momentum of the 1st cart

$p_2$ is the momentum of the 2nd cart

The total momentum of the system at the beginning, when the spring is compressed, is zero:

$p_i=0$

Since the total momentum must be conserved, we have:

$p_i = p_f\\0 = p_1 + p_2\\\rightarrow p_2 = -p_1$

Which means that the two carts will have equal and opposite momenta.

If a car collides with a moving bus, what type of relationship exists between the force of the car and the force of the bus?.

Troyanec [42]

The correct answer is forces are equal but opposite in direction between car and bus.

What do we mean by Collision?

When two objects collide, forces of equal magnitude and opposite direction are applied to each object. Such pressures frequently result in one thing gaining momentum and gaining speed while the other object slows down (lose momentum).

The force applied to an object to cause an impact—a change in momentum—on it is referred to as the impact force, or momentum. Technically speaking, the Car and the bus would have exerted and felt the same amount of impact force in the event of a collision. Because every action has a corresponding and opposing response, according to Newton's third law.
