Velocity will vary linearly , by definition of acceleration;a = change in velocity / time
Or we can say ; change in velocity = acceleration× time
Final velocity - initial velocity = 4×4=16 m/s
( Since ball start with an acceleration of 4m/s2 , so initial velocity is assumed zero )
Final velocity= 16 m/s
Speed after 4 second will be 16m/s
