Your neighbor Paul has rented a truck with a loading ramp. The ramp is tilted upward at 25掳, and Paul is pulling a large crate up the ramp with a rope that angles 10掳 above the ramp. If Paul pulls with a force of 550 N, what are the horizontal and vertical components of his force? (Force is measured in newtons, abbreviated N.)
Kami is walking through the airport with her two-wheeled suitcase. The suitcase handle is tilted 40掳 from vertical, and Kami pulls parallel to the handle with a force of 120 N. (Force is measured in newtons, abbreviated N.) What are the horizontal and vertical components of her applied force?
