A large cruise ship of mass 6.70 ✕ 107 kg has a speed of 12.4 m/s at some instant.

What is the magnitude of the constant force required to stop it as it undergoes a displacement of 2.90 km?

Step 1

According to the work kinetic energy theorem, the work done on an object is equal to the change in kinetic energy of the object.

Substitute the values,

Step 2

The force exerted on the ship to stop it,

Substitute the values,

Step 3

Hence, negative value indicates that the force is opposite to the displacement of the...
