just part c
A fish swimming in a horizontal plane has velocity V₁ = (4.00 î+ 1.00 j) m/s at a point in the ocean where the position relative to a certain rock is r = (12.01 3.20 j) m. After the fish
swims with constant acceleration for 19.0 s, its velocity is V= (17.0 - 1.00 j) m/s.
(a) What are the components of the acceleration of the fish?
ax = 0.684
ay = -0.105
✔m/s²
✓m/s²
(b) What is the direction of its acceleration with respect to unit vector î?
-8.746
✔ counterclockwise from the +x-axis
(c) If the fish maintains constant acceleration, where is it at t= 30.0 s?
311.894
