Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same
