Please help. I'm stuck! What is the mass of a catamaran moving at 7.65 m/s that has a momentum of 530145 kg x m/s?

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

The friction of the water on a boat produces an acceleration of -10. m/s2. if the boat is traveling at 30. m/s and the motor is shut off, how long it take the boat to slow down to 5.0 m/s?
