4. Please provide full body diagram with explanation
Transcribed Image Text:**Problem Statement:**
Calculate:
A) The total energy of a 6 kg mass moving straight upward if the mass is moving with a velocity of 60 m/s at a height of 35 m.
B) The maximum height this mass will achieve.
C) The velocity of the mass at a point where the amount of kinetic energy is 80% of the maximum potential energy.
**Solution Approach:**
1. **Total Energy Calculation:**
- Total energy is the sum of kinetic energy and potential energy.
- Kinetic Energy (KE) = \( \frac{1}{2} m v^2 \)
- Potential Energy (PE) = \( mgh \)
2. **Maximum Height:**
- At maximum height, all the kinetic energy will be converted into potential energy.
- Use energy conservation principles to find the maximum height.
3. **Velocity at Specific Energy Condition:**
- Relate KE and PE to find velocity where KE is 80% of the maximum PE.
**Formulas to Use:**
- KE = \(\frac{1}{2} mv^2\)
- PE = \(mgh\)
(Note: Here, \(m = 6 \text{ kg}\), \(v = 60 \text{ m/s}\), \(g = 9.8 \text{ m/s}^2\), and \(h = 35 \text{ m}\).)
For detailed calculations, solve each part using the given values and formulas.
