Science Homework Help

I don’t know how to handle this Physics question and need guidance.

Question 1:

Find A_x and A_y for the vector its magnitude and direction given by A = 3.5 m and Θ= 66º respectively.

• Find magnitude of B and Θ for the vector with components B_x = 75.5 m and B_y = 6.2 m?
• The vector B has components Bx -2.10 m and By = -1.70 m. Find the direction angle, for this vector?

Question 2:

Vectors A and B represent displacements in meter in unit vector notations:

A = 3i – 4j and B = 4i – j

a) Find R= -4A+5B?

b) Find the magnitude of R ?
