A raindrop in a cloud has 320 J of potential energy due to its position above Earth. As the raindrop falls down to Earth, it gains kinetic energy. Approximately how much
kinetic energy does the raindrop have the moment before it makes contact with a
puddle on the ground?
O 0J
O 640J
O 160J
O 320J

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?
