Question

A fish swimming in a horizontal plane has a velocity vo=(4i+j) m/sec at a point in the ocean whose position vector is r0=(10i-4j)m. After the fish swims with constant acceleration for 20 sec, its velocity is v=(20i-5j) m/s. Find 1.The components of the acceleration.2.The direction of the acceleration with respect to the x-axis.3.The coordinates of the fish at t=25 sec and its direction of motion.
