Question

The x component of vector A is 8.7 units, and its y component is -6.5 units The magnitutude of A is closest to

a.9.9 units
b. 7.9 units
c, 8.9 units
d. 11 units
e. 12 units

Answer 1

magnitued = sqrt((8.7)^2 + (-6.5)^2) = sqrt(75.69 + 42.25) = sqrt(117.94) = 10.86 units.

The magnitutude of A is closest to 11 units.
