an object in equilibrium has 3 forces exerted on it. a 200N force acts at 65 degrees from the positive x-axis and an 150N force acts at 20 degrees from the positive x-axis. what are the magnitude and direction of the third force?

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?
