Answer:
Total mechanical energy = 225 J
Explanation:
Given:
Mass of duck (m) = 2 kg
Speed of duck (v)= 5 m/s
Height of duck from ground (h) = 10 m
Gravitation acceleration (g) = 10 m/s²
Find:
Total mechanical energy
Computation:
Total mechanical energy = Kinetic energy + Potential energy
Total mechanical energy = (1/2)mv² + mgh
Total mechanical energy = (1/2)(2)(5)² + (2)(10)(10)
Total mechanical energy = 25 + 200
Total mechanical energy = 225 J
