A 5.0 kilogram block is initially at rest on the surface of a smooth frozen lake. Mary applies a 7.0 N horizontal force directed North (i.e., along the positive y-axis) and Renaldo applies a 5.0 N horizontal force directed West (i.e., along the negative x- axis).
a) Find the total horizontal force on the box? Write your answer in standard polar form.
b) Find the magnitude and direction of the resulting acceleration of box? Write your answer in standard polar form.
