An object is moving east, andits velocity changes from 65 m/s to 25 m/s in 10 seconds. Which describes the acceleration?
O negative acceleration of 4 m/s?
O positive acceleration of 4 m/s?
O positive acceleration of 9 m/s?
O negative acceleration of 9 m/s

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

temp rises, and expansion

the answer to this is proletariats.

hope this : )
