Question

A vector has an x-component of +3 m, a y-component of +4 m, the resultant vector has a magnitude of a 1 m b 7 m c 5 m d 8 m

Answer 1

Step-by-step explanation:

Given

x component = +3m

y component = +4m

Required

The resultant vector has a magnitude

This can be gotten using the pythagras theorem as shown;

R = √x²+y²

R = √3²+4²

R = √9+16

R = √25

R = 5 m

Hence the resultant vector has a magnitude of 5m
