A speedboat moves on a lake with initial velocity vector U1x = 8.71 m/s and U1, y = -2.37 m/s, then accelerates for 5.89 s at an average acceleration of aav, x = -0.101 m/s and dav,y = 0.104 m/s. What are the components of the speedboat's final velocity, V2,x and U2,y? U2,x= Determine the speedboat's final speed v. U2 = m/s m/s V2.y = m/s
