Chapter 28, Problem 39P(choose chapter or problem)
A boat can travel \(2.30 \mathrm{~m} / \mathrm{s}\) in still water.
(a) If the boat points its prow directly across a stream whose current is \(1.20 \mathrm{~m} / \mathrm{s}\), what is the velocity (magnitude and direction) of the boat relative to the shore?
(b) What will be the position of the boat, relative to its point of origin, after 3.00 s? (See Fig. 3–30.)

ANSWER:
Step 1 :In this question , a particle is rotating in circle with centripetal acceleration ofa = 8.0 m/s 2We need to infer what would happen if we double the radius of the circle withoutchanging its speedIn the second scenario we need find what would happen if we double the speed of theparticle without changing the radius of the circle
