"The graphical method of adding vectors helps us in visualizing the vectors and the resultant vector.But, sometimes, it is tedious and has limited accuracy."
a)Name the alternative method of vector addition.
b)Write a mathematical expression to find resultant of two vectors.
c)A particle is moving eastward with a velocity of `5m/s`.If in `10s`,the velocity changes by `5m/s` northwards,what is the average acceleration in this time.
