The Gravitational Potential Energy is 29400 joules
Step-by-step explanation:
The Gravitational Potential Energy P.E = m g h, where
1. m is the mass
2. g is the acceleration of gravity
3. h is the height
∵ The mass of the hiker is 50 kg
∵ The height of the cliff is 60 meters
∵ g = 9.8 m/s²
- Substitute these values in the rule above
∴ P.E = 50 × 9.8 × 60
∴ P.E = 29400 joules
The Gravitational Potential Energy is 29400 joules

Step-by-step explanation:
Area of the shaded region = area of the outer square - area of the inner square
= 22×22 - 15×15 sq ft
= 484 - 225 sq ft
= 259 sq ft
