1. A 30 cm spring with constant 70 N/m is compressed to 10 cm and placed between two carts. Cart A has mass m Skg and mg is unknown. Initially the system is at rest. After it is released it is observed that cart A has three times the velocity of cart B. a) What force must be exerted initially to keep the spring compressed? b) What is the work done to compress the spring? c) By considering conservation of...

A spring with spring constant 28 N/m is compressed a distance of 7.5 cm by a ball with a mass of 201.5 g (see figure below). The ball is then released and rolls without slipping along a horizontal surface, leaving the spring at point A. The process is repeated, using a block instead, with a mass identical to that of the ball. The block compresses the spring by 7.5 cm and is also released, leaving the spring at point A....

In the figure, a block of mass m = 11 kg is released from rest on a frictionless incline of angle θ = 26°. Below the block is a spring that can be compressed 3.4 cm by a force of 320 N. The block momentarily stops when it compresses the spring by 5.3 cm. (a) How far does the block move down the incline from its rest position to this stopping point? (b) What is the speed of the block...
