Please help Boat A and Boat B have the same mass. Boat A's velocity is three times greater than that of Boat B. Compared to the
kinetic energy of Boat B, the kinetic energy of Boat A is
O one-third as much
O three times as much,
O six times as much
O nine times as much

D nine times as much

Explanation:

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
