1. A 0.234-kg cart is traveling on a frictionless, level track with an initial velocity of 1.23 m/s to the right, as shown in the top image in the figure below. After colliding with a spring attached to a wall (center image), the cart moves back to the left with a velocity of 1.23 m/s (bottom image).   Determine the kinetic energy of the cart before and after its collision. Is the collision elastic? Show enough work to justify your answers.   Calculate the linear momentum vector of the car before and after its collision. Show your calculations.   Why is the total linear momentum not conserved here? Compare your answer with what you said for question 1(a).

Question

1. A 0.234-kg cart is traveling on a frictionless, level track with an initial velocity of 1.23 m/s to the right, as shown in the top image in the figure below. After colliding with a spring attached to a wall (center image), the cart moves back to the left with a velocity of 1.23 m/s (bottom image).

 

Determine the kinetic energy of the cart before and after its collision. Is the collision elastic? Show enough work to justify your answers.

 

Calculate the linear momentum vector of the car before and after its collision. Show your calculations.

 

Why is the total linear momentum not conserved here? Compare your answer with what you said for question 1(a). Hint: See the textbook section 8.2 and what it says about the conservation of momentum principle and when the total momentum is constant.
