A .500 kilogram cart traveling to the right of a horizontal frictionless surface at 2.20 meters per second collides head on with a .800 kilogram cart moving to the left at 1.10 meters per second. what is the magnitude of the totak momentum of the twi cart systemafter the collision?

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
