A 7.64-kg mass is moving in an idealized frictionless tube. Initially, the tube runs straight for 1.24 meter horizontally at ground level before rapidly curving to turn vertically upwards, as shown in the figure. The vertical portion of the tube is completely filled by a relaxed spring with a spring constant of 2.20e+3 N/m. The mass reaches a maximum height of 0.233 meters. Assume that the mass immediately begins to compress the spring as it starts to move vertically. Calculate the initial velocity of the mass. [Note: this question may contain more information than is necessary to solve to problem] Y Lx k llllllllll g Image size: S M L Max m Consider the mass-on-a-spring system as shown in the figure below. The spring has a spring constant of 1.55e+3 N/m, and the block has a mass of 1.25 kg. There is a constant force of kinetic friction between the mass and the floor of 4.11 N. Starting with the spring compressed by 0.190 m from its equilibrium position, how far will the block travel once it leaves the spring? (Assume that block leaves the spring at at the spring's equilibrium position, marked x=0 in the figure. Give your answer as the distance from the equilibrium position to the final position of the block.) www. m x=0 Image size: S M L Max
