A fish swimming in a horizontal plane has velocity (4.00i + 1.00j) m/s at a point in the ocean where the position relative to a certain rock is r(initial)=(10.0i - 4.00j)m. After the fish swims for 20.0 s, its velocity is v=(20.0i - 5.00j) m/s. a)What are the components of acceleration? b) What is the direction of acceleration with respect to the unit vector i? c) If the fish maintains constant acceleration, where is it at t=25.0 s, and in what direction is it moving?
