Final answer:
To find the gravitational potential energy (GPE) of a small rabbit jumping 4 meters into the air, use the formula G.P.E. = mgh. After calculation, the GPE is found to be 70.4 Joules.
Step-by-step explanation:
The question involves calculating the gravitational potential energy (GPE) of a rabbit on Earth. The formula for GPE is G.P.E. = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height. Using the given values: mass (m) of the rabbit as 1.8 kg, acceleration due to gravity (g) as 9.8 m/s², and the height (h) as 4 meters, we can perform the calculation.
The correct calculation is: G.P.E. = (1.8 kg) × (9.8 m/s²) × (4 m) = 70.4 Joules. Thus, the rabbit has a GPE of 70.4 J when it jumps 4 meters into the air on Earth.
