Explain in terms of the arrangementbof particles the kinetic theory of matter

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s. a. determine jay’s mass. b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?
