A force of 540 N stretches a certain spring a distance of 0.150 m. What is the potential energy of the spring when a 60.0-kg mass hangs vertically from it? Solution:, where y is the vertical distance the spring is stretched when the weight . w = mg is suspended. , and , where x and F are the quantities that "calibrate" the spring. Combining: mass m = 100 kg is hung on a spring of stiffness 10 kN/m. It is pulled down 50 mm below its. static equilibrium position and released. There is a frictional resistance which is proportional to the. velocity and is 360 N when the velocity is 1 m/s. (1) write down the equation of motion and find its.

A block with mass M = 5.0kg rests on a frictionless table and is attached by a horizontal spring (k = 130 N/m) to a wall. A second block, of mass m = 1.25 kg, rests on top of M. The coefficient of static friction between the two blocks is 0.30. What is the maximum possible amplitude of oscillation...
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 with the spring between them as shown in the gure below. A cord initially holding the blocks together is burned; after that happens, the block of mass 3m moves to the right Block B, (8.0 kg), is attached to the dangling end of the string over a frictionless pulley. The acceleration of B is: F Net = m T a (80-100sin30°) – F f = (10+8) a (30) - µ 100cos30° = 18a a = 0.7 m/s2 down 37. An ideal spring is hung vertically from the ceiling. When a 2.0-kg mass hangs at rest from it, the spring is extended 6.0 cm from
