solve the following

I. Problem Solving. Solve the following problems. Provide all necessary data and show complete solutions. 1. (Magnitude of the Sum of Two Vectors) Find the magnitude and direction of the two forces 20 N and 25 N acting at an angle 60 to each other. 2. (Magnitude of the Sum of Two Vectors) Find the magnitude and direction of the resultant of two forces 30 N and 40 N acting at right angles to each other. 3. (Force and Displacement at an Angle) A sailor pulls a boat a distance of 30 m along a dock using a rope that makes a 25 angle with the horizontal. How much work does the sailor do on the boat it he exerts a force 255 N on the rope? +y +x 25.0 F F cos 25.0 4. (Power) An electric motor lifts an elevator 9 m in 15 s by exerting an upward force of 1.20 x 104 N. What power does the motor produce in KW? F d F 5. (Acceleration) A 2.49 x 104 N Rolls-Royce Phantom travelling in the + x-direction makes an emergency stop; the x-component of the net force acting on it is -1.83 x 10* N. What is its acceleration
