The target is six meters away, and I am able to consistently throw the axe with a horizontal initial velocity of nine meters per second. How long will it take for the axe to reach target? b. What angular speed do I need to give the axe in order for it complete one revolution while traveling to the target? c. Flicking my wrist as I release, I gave the axe that angular speed with a constant angular acceleration over one quarter revolution. What angular acceleration did I give to the axe?

Question

Please do part two of this problem for me. I submitted the first picture with problem one to help give you a background for the problem and understand what is going. I did part 1 on my own already

### Diagram Explanation

The image showcases a simple mechanical diagram involving an arm holding an axe. It can be broken down as follows:

- **Shoulder Joint**: Represented by a circle on the left side, indicating the pivot point.
- **Arm**: Illustrated as a horizontal line extending from the shoulder joint to the axe.
- **Axe**: Positioned at the end of the arm, exerting a downward force.
- **Deltoid Muscle**: Illustrated with a red arrow above the arm, connected at an angle, showing the direction of force.

### Questions and Transcription

1. **a.**
   - **Scenario**: Holding a 1.5-pound (0.67-kg) axe at arm’s length, with the axe’s center of mass 75 centimeters from the shoulder.
   - **Question**: What torque does the axe exert about the axis of the shoulder?

2. **b.**
   - **Scenario**: The deltoid is 15 cm from the shoulder joint, pulling at a 30-degree angle.
   - **Question**: What force does the deltoid need to exert to hold the axe out?

3. **c.**
   - **Question**: What third force must the shoulder joint exert to hold the arm out like this? Illustrate the direction.

### Problem:

2a. The target is six meters away, and I am able to consistently throw the axe with a horizontal initial velocity of nine meters per second. How long will it take for the axe to reach the target?

2b. What angular speed do I need to give the axe in order for it to complete one revolution while traveling to the target?

2c. Flicking my wrist as I release, I gave the axe that angular speed with a constant angular acceleration over one quarter revolution. What angular acceleration did I give to the axe?
