m= 60g = 60/1000 Kg = 0.06 Kg
v = 2cm3 = 2 * (0.01^3) m3 = 2 *10^-6 m3
Density= m/v = 6 * 10^-2 / 2 *10^-6 = 3 *10^4 Kg/m3

Answer:
The ocean liner
Explanation:
Given that,
The mass of the bullet, m = 0.0014 Kg
The velocity of the bullet, v = 396 m/s
The mass of the ocean liner, M = 7.1 x 10⁷ Kg
The velocity of the ocean liner, V = 13 m/s
The kinetic energy is given by the formula,
K.E = 1/2 mv²
1) The kinetic energy of the bullet,
K.E = 1/2 x 0.0014 x 396²
= 109.775 J
2) The kinetic energy of the ocean liner,
K.E = 1/2 x 7.1 x 10⁷ x 13²
= 6 x 10⁹ J
Hence, the ocean liner has more kinetic energy.
