If a 3-kg rabbit's leg muscles act as imperfectly elastic springs, how much energy will they hold if the rabbit lands from a height of 0.5 m and its legs are compressed by 0.2 m?

U = 14.7 J

Explanation:

Loss in gravitational potential energy is stored in the form of potential energy of rabbit legs

So here we will have by energy conservation

gravitational potential energy = energy stored in the legs

so here we will have

gravitational potential energy given as

m = 3 kg

g = 9.81 m/s/s

h = 0.5 m

now we have

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
