Question 3 A fish swimming in a horizontal plane has velocity vo = (4î+) m/s at a point in the ocean whose
displacement from a certain rock is ro = (10î – 4ſ)m. After swimming with constant acceleration for
20s, its velocity is v = (20î - 5ſ) m/s.
a) What are the components of the acceleration?
b) What is the direction of the acceleration with respect to unit vector i?
c) Where is the fish at t = 25s and in what direction is it moving?
