Q.	A fish swimming in a horizontal plane has velocity Vo = ( 4.0i  +  1.0j ) m/s at a point in the ocean whose position vector is ro = ( 10.0i -  4.0j ) m relative to a stationary rock at the shore. After the fish swims with constant acceleration for 20.0 s, its velocity is v = ( 20.0i  -  5.0j ) m/s.

a)	What are the components of the acceleration?

b)	What is the direction of the acceleration with respect to the fixed x-axis.
