Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

**Problem Statement:**

The cart impacts the safety barrier with speed $ v_0 = 3.25 \, \text{m/s} $ and is brought to a stop by the nest of nonlinear springs which provide a deceleration $ a = -k_1 x - k_2 x^3 $, where $ x $ is the amount of spring deflection from the undeformed position and $ k_1 $ and $ k_2 $ are positive constants. If the maximum spring deflection is 540 mm and the velocity at half-maximum deflection is 2.84 m/s, determine the values for the constants $ k_1 $ and $ k_2 $.

**Diagrams and Explanations:**

- The diagram shows a cart moving with initial speed $ v_0 $ towards a safety barrier composed of nonlinear springs.
- The springs are initially in the **"undeformed position"**.
- The distance $ x $ represents the deflection of the springs from their undeformed position when impacted by the cart.

**Given Data:**

- Initial speed of the cart, $ v_0 = 3.25 \, \text{m/s} $
- Maximum spring deflection, $ x_{\text{max}} = 540 \, \text{mm} = 0.54 \, \text{m} $
- Velocity at half-maximum deflection, $ v(0.27 \, \text{m}) = 2.84 \, \text{m/s} $

**Objective:**

- To determine the values for the constants $ k_1 $ and $ k_2 $.

**Answers:**

- $ k_1 = \boxed{\text{ }} \, \text{s}^{-2} $
- $ k_2 = \boxed{\text{ }} \, \text{m}^{-2}\text{s}^{-2} $
