Explanation / Answer

here,

mass , m = 6.9 * 10^7 kg

speed , v = 12.6 m/s

a)

the ship's kinetic energy , KE = 0.5 * m * v^2

KE = 0.5 * 6.9 * 10^7 * 12.6^2 J

KE = 5.48 * 10^9 J

b)

the work done , W = change in kinetic energy

W = 0 - KE = - 5.48 * 10^9 J

c)

s = 2300 m

the magnitude of constant force required , F = |W/s|

F = 5.48 * 10^9 / 2300 N

F = 2.38 * 10^6 N
