:Both potential energy because it still has a distance to move before it hits the ground and kinetic energy because its moving.

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?

Atrain departs from its station at a constant acceleration of 5 m/s. what is the speed of the train at the end of 20s?
