Q: When the hammer of 15kg is raised to a height of 10m, find the potential energy obtained by it?
  • A. 1500J
  • B. -150J
  • C. -1500J
  • D. 150J
Correct Answer: Option A - Potential energy = m×g×h Here, m =15 kg, h = 10m and g = 10 m/s² = 15×10×10 = 1500J Potential energy = m×g×h Here, m =15 kg, h = 10m and g = 10 m/s² = 15×10×10 = 1500J
A. Potential energy = m×g×h Here, m =15 kg, h = 10m and g = 10 m/s² = 15×10×10 = 1500J Potential energy = m×g×h Here, m =15 kg, h = 10m and g = 10 m/s² = 15×10×10 = 1500J

Explanations:

Potential energy = m×g×h Here, m =15 kg, h = 10m and g = 10 m/s² = 15×10×10 = 1500J Potential energy = m×g×h Here, m =15 kg, h = 10m and g = 10 m/s² = 15×10×10 = 1500J
