A Christmas sphere will break if dropped on hardwood floor with a velocity of 2.0 m/s. Mar Estefanla is decorating her Christmas tree when her cat, Missy, taps a sphere, causing it to fall 0.15 m from a tree branch to

the floor.

What is the velocity of the sphere right before it hits the ground? Acceleration due to gravity vs 9.8 m/s

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?
