well as we know that velocity is a vector hence it has magnitude as well as direction. Let us assign sign conventions for direction of velocities in this example: Let eastward velocity be positive and westward be taken as negative. Initial Velocity:-20 Final Velocity:+5 CHange in velocity=Final velocity-Initial Valocity Change in Velocity=5-(-20)=25m/s So change in velocity will be 25m/s
