A fish swimming in a horizontal plane has velocity i = (4.00 + 1.00 ) m/s at a point in the ocean where the position relative to a certain rock is i = (14.0 ? 4.20 ) m. After the fish swims with constant acceleration for 15.0 s, its velocity is = (25.0 ? 1.00 ) m/s.
(a) What are the components of the acceleration of the fish?
ax =
ay =
(b) What is the direction of its acceleration with respect to unit vector ?
(c) If the fish maintains constant acceleration, where is it at t = 28.0 s?
x =
y =
(d) In what direction is it moving?
