The boat weighs 1200 N with its passengers. Suppose that the boat is moving at a constant speed of 20 m/s in a circular path with radius

𝑅 = 40 𝑚.

For a. ask yourself if the boat is accelerating in the tangential direction.

For b. Normal force is mass.v²/R and here, mass.g = 1200 N, v = 20 m/s, R = 40m.
