I know that the answer is a but what are the steps of solving it??
Q11 A fish swimming in a horizontal plane has an initial velocity v, (4.0 i+1.0 j) m/s at a point in the ocean. After the fish swam for 20 s, its velocity is v (20î- 5.0 j) m/s. If the fish maintains constant acceleration, what is its velocity in (m/s) at-25 s A) 24 i 6.5 j B) 16i.+ 9.5 j C) 11 i-8.8 j D) 331+17 j E) 271-16j
