Question

In the diagram above (not to scale), = 12.57 meters/second and
= 5.21 meters/second. What is the value of the resultant vector ?
A.
7.36 meters/second
B.
11.23 meters/second
C.
17.78 meters/second
D.
5.21 meters/second
E.
6.67 meters/second

Answer 1

without a diagram, all we can say is that
12.57 - 5.21 <= |R| <= 12.57 + 5.21
so any of the choices A,B,C is possible. I suspect B, since the others are extreme cases.
