Asked by Lovelle
vector a has magnitude 1 and vector b has magnitude 16m. Their scalar product is 90.0m^2. What is the magnitude of the vector product between these 2 vectors?

scalar product or dot product:
a∙b = |a| |b|cosØ, where Ø is the angle between then
1(16)cosØ = 90
cosØ= 90/16 = 5.625 , which is not possible, since cos(anything) falls between -1 and +1
