Answer:
Step-by-step explanation:
The potential energy gained by the monkey can be calculated using the formula:
potential energy = mass x gravity x height
where the mass is 50 kg, the height is 300 m, and the acceleration due to gravity is 10 m/s².
Substituting these values into the formula, we get:
potential energy = 50 kg x 10 m/s² x 300 m = 150,000 J
Therefore, the potential energy gained by the monkey is 1.5 x 10⁵ J.
Hence, the answer is option (2) 1.5×10⁵J.
