Summary of Kinetic Energy Calculations

Given Values

  • Energy (E): 18,000 J
  • Mass (m): 60 kg

Kinetic Energy Calculation

  • Formula for Kinetic Energy (KE):
    KE=12mv2KE = \frac{1}{2}mv^2
  • KE for m = 60 kg, v = 16.67 m/s:
    KE=0.5×60×(16.67)2=5,040,000 JKE = 0.5 \times 60 \times (16.67)^2 = 5,040,000 \text{ J}

Additional Given Values

  • Mass (m): 1000 kg
  • Velocity (v): 12.60 m/s
  • Additional speed: 2.60 m/s

Summary

  • Kinetic energy values derived from given masses and speeds must utilize the kinetic energy formula for accurate calculations.
