Part B (Mechanical Energy and Conservation of Energy) Problem B1: A block of mass m = 0.2kg is held against but not attached to a spring of so compressed by 20cm, as show below. When released, the block slides som the rough incline before coming to rest. but not attached to a spring of stiffness constant ka 50cm 20cm * = 0, Usp = 0 Low Ug = 0 Use mechanical energy for non-conservative force to find: 1) The force...
using the conservation of energy 3. [7] The two blocks shown below have masses m = 1.0 kg and m2 = 3.0 kg. Assume that 0 = 25°, k = 16 N/m, and H=0.11 between mi and the incline. Neglect friction in the pulley and assume that the pulley and string and cable are massless. If this system is released initially at rest with the spring in its equilibrium position (no stretch), what is the speed of m2 after it...

Its motion is halted by a spring (k=5N/m). ww 1) What is the speed of the block just as it reaches the spring? 2) Find the maximum compression of the spring
Two blocks m1 and m2 with masses 50 kg and 100 kg respectively are connected by a string over a pulley that is frictionless with negligible mass. The 50 kg block slides on a 37 degree incline that has a coefficient of kinetic friction of 0.25. This block is also attached to a wall at the base of the incline by an ideal spring that has a spring coefficient of 100 N/m. The system is released from rest with a...
3. Two blocks of masses m and 3m are placed on a frictionless horizontal surface. A light spring is attached to the more massive block, and the blocks are pushed together and connected with a cord. The spring has a spring constant k, and while the blocks are pushed together, the spring is compressed over a distance d. At a moment in time t-0, the cord is cut, the spring expunds, and the blocks are sliding away from each other....
Problem 31 mi ma Two blocks ma = 4 kg and m2 = 9 kg are initially arranged as shown in the figure. They are tied to a massless rope going around the pulley. The pulley has a form of a cylinder e with a mass of M = 8 kg and radius of R = 40 cm. Both the incline and the horizontal surface have a coefficient of kinetic friction uk = 0.15. The incline is at the angle...
Problem 3. (4.0 pts.) Two blocks of masses mi = 1.35 kg and m2 = 1.27 kg are connected through a pulley so that one of the blocks is hanging freely and the other one is located on the horizontal plane, as shown in Fig. 1. The friction coefficient for the first block is jis = 0.37. The system is released and block m; goes down by d = 43.2 cm. (a) Find the acceleration of the blocks. (6) What...
Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other by a string that passes through a massless pulley. The stiffness constant of the spring attached to m1 and the wall is k=120N/m and the coefficient of kinetic friction between m1 and the surface is given to be μk=0.2. If the system is released from rest when the spring is at its equilibrium length and m2 is at a...
