Thread: Having trouble with a couple vector problems

Hello! I'm having some trouble with these couple of problems. It would be greatly appreciated if anyone could show me the steps to complete them. Thank you so much!


1. V_1 = <-3,3> V_2= <4,-1> V_3= <0,-5> Find -2V_1 -3V_2 + 4V_3


2. Vector V1 has amagnitude of 11, with an angle of 45 degrees. Vector V2 has a magnitude of 4with an angle of 90 degrees. Find the magnitude & angle of a vector thatwill bring the 3 vectors into equilibrium.

1. To multiply a vector by a scalar, you need to multiply each element by that scalar.

To add or subtract vectors, you need to add or subtract the corresponding elements.

2. Start by drawing a triangle of vectors and writing all three vectors in Cartesian form.
