1.2 kg cart slides down frictionless ramp from a height of 1.8m and then onto a horizontal surface where it has a head-on elastic collision with a stationary 2.0kg cart cushioned by an ideal Hooke's Law spring. Maximum compression of spring is 2.0 cm

But this did not get me the answer
The spring constant after a collision is used to calculate the amount of energy stored in the spring during the collision. This information is important in understanding the mechanics of the collision and can be used to predict the behavior of the system in future collisions.
The spring constant can be determined by measuring the displacement of the spring caused by the collision and calculating the ratio of the applied force to the displacement. This can be done using a force sensor and a motion detector, or by analyzing video footage of the collision.
Some factors that can affect the accuracy of determining the spring constant after a collision include the type and condition of the spring, the precision of the measurement tools used, and external factors such as air resistance or friction.
Yes, the spring constant can change after a collision. This is because the collision can alter the physical properties of the spring, such as its stiffness or elasticity. Additionally, external factors such as temperature or wear and tear can also affect the spring constant.
Hooke's Law states that the force applied to a spring is directly proportional to the displacement of the spring. By determining the spring constant after a collision, we are essentially calculating the constant of proportionality in this relationship, which can then be used to predict the behavior of the spring in future situations.
