Question

find the resultant velocity v1 vector and v2 vector are equal magnitude

Answer 1

Answer:

V1,v2 be two vectors

if their magnitudes are equal then,V1=v2=v

resultant vector=✓v^2+v^2+2v^2cos theta

=✓2v^2+2v^2 cos theta

=✓2v^2(1+cos theta)

where,theta is the angle between the two vectors
