A speedboat moves on a lake with initial velocity vector, Ask an Expert

Academics

A speedboat moves on a lake with initial velocity vector V1x= 9.27m/s and V1y= -2.83m/s, then accelerates for 5.79s at an average acceleration of Ax= -0.106m/s^2 and Ay= 0.105m/s^2. What are the components of the speedboat's final velocity, V2x and V2y? What is the speedboat's final speed???
