An ice cube and rubber ball of identical mass and similar size begin at rest at the top of a ramp. The cube slides down the ramp without friction. The rubber ball rolls down the ramp without slipping. Which object, if any, will have the greater translational kinetic energy at the end of the ramp? the cube will have more translational kinetic energy since all of the system's initial gravitational potential energy turned into translational kinetic energy the ball will have more translational kinetic energy since it also gains rotational kinetic energy O the cube will have more translational kinetic energy since it's system started with more initial rotational kinetic energy both objects will have the same translational kinetic energy since both systems started with the same initial gravitational potential energy
Ball A moves straight to the right at constant velocity toward a different ball B floating at rest in space. The direction of the initial velocity of ball A can be considered the positive x- axis. After the two balls collide, ball A moves up and to the right (at an angle above the positive x-axis) and ball B moves down and to the right (at an angle below the positive x- axis). What can be said about the momenta of each ball after the collision? the horizontal momentum of ball A and B are identical O the horizontal momentum of ball A must still be the same as it was for ball A before the collision the total momentum of ball A must be equal to the total momentum of ball B O the vertical momentum of ball A must be equal and opposite to the vertical momentum of ball B
A carousel is a rigid disk that spins horizontally at a constant speed. Person A is standing on the carousel 1.00-m from the center. Person B is standing 2.00 m from the center. Person A will have [Select] and will have [Select] less tangential speed than person B more tangential speed than person B the same tangential speed as person B
