Two blocks of mass m are brought close to each other with a spring (mass negligible) compressed between then. The spring has potential energy 1/2kx2, where k and x are the force constant and the compression of the spring. The system is held together by a string (mass negligible) that opposes the outward force of the spring. When the string is cut, the spring expands to to its natural length (where it stores no more potential energy), and the two blocks fly apart with total kinetic energy equal to the potential energy that had been stored in the spring. In terms of the mentioned quantities, find the mass of the system before the string was cut.
In a study of the biomechanics of thetug-of-war, a 2.0-m-tall, 80.0 kg competitor in the middle of the line isconsidered to be a rigid body leaning back at an angle of 30.0° to the vertical. The competitor is pulling ona rope that is held horizontal a distanceof 1.5 m from his feet (as measuredalong the line of the body). Atthe moment shown in the figure, theman is stationary and the tension in therope in front of him is T1 = 1160 N.Since there is friction between therope and his hands, the tension in therope behind him, T2, is not equal to T1.His center of mass is halfway betweenhis feet and the top of his head.
