I have some question related to vectors.
1)How will you find a vector(A) if you given another vector(B) in +x-direction to give a resultant(R) at θ(any degree)?
2)A child is holding a wagon from rolling straight back down a driveway that is inclined at 20° to horizontal. If the wagon weighs 150N, with what force must the child pull on the handle if the handle is at 30° above the incline?(This question is asked by a friend. I tried but I am not able to get answer. I told him that I will ask an expert then tell you.)
3)Find the magnitude and angle of R if R=7.0i-12j
I did not get to angle, my θ=-1.042. Is my answer wrong?
Last question
4)If you give a vector in form of its magnitude and ask to write it in the form of unit vectors(i,j,k) then how will do it?
Any help is appreciable. Thanks in advance.
