Two forces, F1 vector and F2 vector, act at a point. F1 vector has a magnitude of 8.40N and is directed at an angle of 65.0 degrees above the negative x axis in the second quadrant. F2 vector has a magnitude of 7.00N and is directed at an angle of 53.9 degrees below the negative x axis in the third quadrant.
1) What is the x component of the resultant force?
2) What is the y component of the resultant force?
3) What is the magnitude of the resultant force?
A ski jumper has 1.2 ´ 10 J of potential energy at the top of the ski jump. The friction on the jump slope is small, but not negligible. What can you end about the ski jumper's kinetic energy at the bottom of the jump.
