For the vectors a = (2.8 m)i + (3.4 m)j, and b = (6.0 m)i - (2.0 m)j,?

Question

give the x and y components, magnitudes, and directions of the following vector operations:
a + b
(x component)
(y component)
(magnitude)
° (direction from the positive x axis)

Answer 1

a+b= 8.8m i+1.4m j
x comp.= 8.8m
y comp = 1.4m magnitude = m*sqrt( 8.8^2+1.4^2)=8.91*m
tang @= 1.4/8.8=0.1591 so @=0.1578 rad
