Q1. Two blocks of the same mass m, joined by a spring of negligible mass and with spring constant k, are being lowered at the end of a string with a downward acceleration of g/4. Beside how much is spring stretched as the blocks are lowered? The spring exerts an upward force of F on the top block.

2. A halfback on an apparent breakaway for a touchdown is tackled from behind. If the halfback has a mass of 98 kg and was moving at 4.1 m/s while he was tackled by an 85 kg cornerback running at 5.5 m/s in the similar direction, what was their mutual speed at once after the touchdown-saving tackle?
