A200 n force is applied to an object (that is at the origin) at 30 degrees above the horizontal on the positive x axis. a second force is applied at 20 degrees below the horizontal on the negative x axis. in order for the object to be in equilibrium in the y direction, what must the magnitude of this force be?

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?

If anyone who can me with this hw? i would really appreciate it
