Q
Q: What is the gravitational potential energy of a mass of 2 kg at a height of 10 m above the ground? (g = 9.8 m/s^2)
Solution:
Gravitational potential energy (U) = mgh = 2 kg * 9.8 m/s^2 * 10 m = 196 J.
Steps: 7
Show Steps
Step 1: Identify the mass (m) of the object. In this case, the mass is 2 kg.
Step 2: Identify the height (h) above the ground. Here, the height is 10 m.
Step 3: Identify the acceleration due to gravity (g). It is given as 9.8 m/s^2.
Step 4: Use the formula for gravitational potential energy (U), which is U = mgh.
Step 5: Substitute the values into the formula: U = 2 kg * 9.8 m/s^2 * 10 m.
Step 6: Calculate the result: 2 * 9.8 * 10 = 196 J.
Step 7: Conclude that the gravitational potential energy is 196 Joules.
