Q
Q: A 3 kg object is dropped from a height of 10 m. What is the potential energy at the top? (2022)
Solution:
Potential Energy = mass × g × height = 3 kg × 10 m/s² × 10 m = 300 J
Steps: 6
Show Steps
Step 1: Identify the mass of the object. In this case, the mass is 3 kg.
Step 2: Identify the height from which the object is dropped. Here, the height is 10 m.
Step 3: Identify the acceleration due to gravity (g). It is approximately 10 m/s².
Step 4: Use the formula for potential energy: Potential Energy = mass × g × height.
Step 5: Substitute the values into the formula: Potential Energy = 3 kg × 10 m/s² × 10 m.
Step 6: Calculate the potential energy: 3 × 10 × 10 = 300 J.
