Two spherical objects differ in size and mass. Object A has a mass that is eight times the mass of B. the radius of object A is twice the radius of object B. How do their densities compress?

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?

Discuss how the hardness or softness of the landing surface is related to the time required to stop the egg
