Question
**Problem 4:**

A ball with an initial velocity of 6.5 m/s and mass 1.7 kg moves at an angle of 59.5° above the horizontal. The ball hits a vertical wall and bounces off so that it is again moving at 59.5° above the horizontal with the same speed. See the figure.

**Question:**

What is the magnitude of the impulse delivered by the wall, in kilogram meters per second?

\[ J = \]

**Diagram Explanation:**

The diagram shows a ball approaching a wall and then rebounding off. The ball's motion is indicated by two arrows: one showing its movement towards the wall and another showing its movement away. Both arrows form an angle \( \theta = 59.5° \) with the horizontal. The angle is relative to the horizontal both before and after the impact.

**Calculator Interface:**

A calculator is provided on the page with buttons for various trigonometric functions (sin, cos, tan, etc.), numerical digits, and operations. Users can input their answers in either degrees or radians.

**Submission Details:**

- The field for inputting the impulse magnitude \( J \).
- Options to submit the solution, request a hint with a 1% deduction per hint, or receive feedback with the same deduction.

**Additional Information:**

- Homework Set 6 with a start and due date is displayed at the top.
- A note indicates a potential grade deduction for using hints and feedback.

**Note:**

Ensure to calculate the change in momentum in the horizontal direction to determine the impulse delivered by the wall.
