3. A block of mass m is attached to the end of a spring with spring constant k. The mass is given an initial displacement x, from equilibrium, and an initial speed vo. Ignoring friction, use energy methods to find a. maximum speed b. maximum stretch from equilibrium in terms of the other variables. eeee 1. A spring has a spring constant k of 82.0 N/m. How much must this spring be compressed to store 35.0J of potential energy? 2. A spring with k = 63N/m hangs vertically next to a ruler. The end of the spring is next to the 15cm mark on the ruler. If a 2.5kg mass is now attached to the end of the spring, where will the end of the spring line up with the ruler marks? 4. Two masses are connected by a string as shown in the figure below. Mass m = frictionless inclined plane while m = 5.0kg is initially held at a height of h =.75m above the 4kg rests on a floor. a. if m, is allowed to fall, what will be the resulting acceleration of the masses? b. if the masses were initially at rest, use con of energy to find the velocity of the masses just before m hits the floor. 1 of energy to the masses e floor. ame MA MB 0 = 32 h 3.
