QUESTION
Determine the magnitude of {\bf{\vec V}}_1 - {\bf{\vec V}}_2 + {\bf{\vec V}}_3.
Determine the magnitude of {bf{vec V}}_1 - {bf{vec V}}_2 + {bf{vec V}}_3. Determine the angle (in degrees) of {bf{vec V}}_1 - {bf{vec V}}_2 + {bf{vec V}}_3Determine the angle (in degrees) of the sum of the three vectors {bf{vec V}}_1 = 4.0,{bf{hat i}} - 9.0,{bf{hat j}},,{bf{vec V}}_2 = {bf{hat i}} + {bf{hat j}}, and {bf{vec V}}_3 = - 1.0,{bf{hat i}} + 5.0,{bf{hat j}}.
Solution:Given: So, Magnitude of Angle of Now, sum of the three vectors, Angle of
