Answer:
The direction of the force is towards the east.
The relative strength of the force acting on the boat is proportional to the acceleration acting on the boat.
Step-by-step explanation:
Given data,
The initial velocity of the sailboat, u = 0 m/s
The final velocity of the sailboat, v = 2 m/s
Let, the time period of the sailboat to reach 2 m/s is, t = 4 s
The acceleration of the sailboat is given by the formula,
a = (v-u)/t
a = (2 - 0)/ 4
a = 0.5 m/s²
The direction of the force is towards the east.
The relative strength of the force acting on the boat is proportional to the acceleration acting on the boat.
