Question

give answer in 2 step with explanation at the end of each step and final answer at the end:+ Draw a diagram showing a block being pushed at a constant speed across a rough surface with a force F. The
frictional force opposing the push is FF. Gravity is pulling down on the block and the surface is pushing up on
the block with a normal force N.. Label the diagram with each of the forces. + If the above block is moving with a
constant speed, what does this say about the net force applied to the block? + Write the Month and Day of the
Assignment Due Date. For example, if the assignment is due on July 15th, then Month = 7, Day = 15. + Foran
object having a mass equal to the month multiplied by the day in kilograms given in the previous section (for our
example of July 15th, the mass would be 7x15 = 105kg), calculate the weight of the object on the planet Mars
assuming acceleration due to gravity is 3.7 m/s2. Show all your work. Do not use 105kg unless the due date is
truly the 15th day of July. * Find an example of a physical force from within the New Testament and discuss the
example. Be sure to provide the scripture reference. Physical force means an event that occurred durin

## Step 1: **Analyzing the Block Diagram and Net Force**

- **Diagram Description:**
  - The block is being pushed rightward with a force $ F $.
  - Frictional force ($ F_F $) acts leftward, opposing the motion.
  - Gravity ($ mg $) pulls downward.
  - The surface pushes upward with normal force ($ N $).
- **Constant Speed:**  
  - If the block moves with constant speed, acceleration is zero.
  - **Net Force:** $ \sum F = ma =  $
  - All forces must balance:
    - Rightward $ F = F_F $ (horizontal forces)
    - Upward $ N = mg $ (vertical forces)

**Explanation:**  
When speed is constant, the push force exactly cancels the friction, and gravity is balanced by the normal force. The net force is zero.

## Step 2: **Calculating Weight on Mars Using Due Date**

- **Assume Assignment Due Date:** Let's say it's **April 10th** (Month = 4, Day = 10).
- **Mass Calculation:**  
  $ \text{Mass} = \text{Month} \times \text{Day} = 4 \times 10 = 40\, \text{kg} $
- **Weight on Mars:**  
  Mars gravity, $ g_{Mars} = 3.7\, \text{m/s}^2 $
  $$
  \text{Weight on Mars} = m \times g_{Mars} = 40\, \text{kg} \times 3.7\, \text{m/s}^2 = 148\, \text{N}
  $$

**Explanation:**  
The weight is mass times gravity. On Mars, you use the local gravity value (3.7 m/s²).

## Final Answers

1. **Net force on the block is zero** because it moves at constant speed; all forces are balanced.
2. **Weight of a 40 kg object on Mars:** $ \boxed{148\, \text{N}} $

### Bonus: Example of Physical Force in the New Testament

- **Example:** The stone being rolled away from Jesus’ tomb (Matthew 28:2).
- **Reference:** “There was a violent earthquake, for an angel of the Lord came down from heaven and, going to the tomb, rolled back the stone and sat on it.” (Matthew 28:2, NIV)
- **Discussion:**  
  The rolling of the stone is a clear example of a physical force (pushing/rolling) in the New Testament.
