Two blocks are initially at rest with a compressed spring between them. when the spring is released, the 2m block moves to the left and the m block moves to the right. this represents an inelastic collision in a closed system. what best describes the blocks after the spring is released? the total energy is zero. the total momentum is zero. the momentum of the m block is zero. the momentum of the 2m block is zero.

Arunner is training for an upcoming marathon by running around a 100-m-diameter circular track at constant speed. let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. the runner starts at (x, y) = (50 m, 0 m) and runs 2.5 times around the track in a clockwise direction.
