Q
Q: What is the potential energy of a 2 kg mass at a height of 5 m? (g = 10 m/s²)
Solution:
Potential energy (PE) = mgh = 2 kg * 10 m/s² * 5 m = 100 J.
Steps: 7
Show Steps
Step 1: Identify the mass (m). In this case, the mass is 2 kg.
Step 2: Identify the height (h). Here, the height is 5 m.
Step 3: Identify the acceleration due to gravity (g). It is given as 10 m/s².
Step 4: Use the formula for potential energy (PE), which is PE = mgh.
Step 5: Substitute the values into the formula: PE = 2 kg * 10 m/s² * 5 m.
Step 6: Calculate the result: 2 * 10 * 5 = 100.
Step 7: Conclude that the potential energy is 100 Joules (J).
