Two pine cones are falling from a pine tree. Both pine cones are falling at the same speed. If Pine Cone 1 has LESS MASS than Pine Cone 2, which pine cone has more kinetic energy?

Pine cone 2 does, the more mass an object has, the more kinetic energy is has.

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
