Answer :
Final answer:
The gravitational potential energy of a 1.9-kg bird nest located 15 m above the ground is closest to choice (c) 284 J, calculated using the formula GPE = mgh.
Explanation:
The question asks about the gravitational potential energy (GPE) of a bird nest located above the ground. GPE can be calculated using the formula GPE = mgh, where m is mass in kilograms, g is the acceleration due to gravity (9.8 m/s² on Earth), and h is the height above the reference point in meters. For a 1.9-kg bird nest located 15 m above the ground, the gravitational potential energy is calculated as follows: GPE = mgh = (1.9 kg)(9.8 m/s²)(15 m) = 279.3 J Since choices (a) 147 J, (b) 220 J, (c) 284 J, and (d) 441 J are given, the closest value to our calculation is (c) 284 J.
