6. a woman takes her dog rover for a walk on a leash. to get the little poco moving forward, she pulls on the leash with a force of 20.0 n at an angle of 37 degrees above the horizonta. how much force is tending to lift rover off the ground? 16.0 n 12.0 n 20.0 n 42.1 n 10. vector a has a magnitude of 12.6 m and a direction of -84.0 degrees. vector b ha a a magnitude of 34.0 m and a direction of -75.0 degrees. what is the resultant magnitude and direction of a vector that is equal to a+b? magnitude 20.6 m direction -71.1 degrees magnitude 46.4 m direction -77 degrees magnitude 20.6 m direction -78.2 degrees magnitude 46.4 m direction 102 degrees
