An object has one force acting on it. it is a 33-newton force pointing downward. to create a net force of zero on the object, which force must be applied to it?

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?

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?
