) While pushing a cart across a floor, Andrea and Jennifer exert forces ⃗ and ⃗ on the cart. Andrea’s force is due north with a magnitude of 130.0 N and Jennifer’s force is 32° west of north with a magnitude of 180.0 N. (a) Find the net force in component form. (b) Find the magnitude and direction of the net force. (c) If Andrea and Jennifer’s housemate, David, disagrees with the move and wants to prevent its relocation, with what force should he push with so the cart does not move? (assume there is not friction on the cart)
