Learning Goal: To understand the use of Hooke's law for a spring. Hooke's law states that the restoring force F on a spring when it has been stretched or compressed is proportional to the displacement of the spring from its equilibrium position. The equilibrium position is the position at which the spring is neither stretched nor compressed. Recall that Fx means that F is equal to a constant times. For a spring, the proportionality constant is called the spring constant and denoted by k. The spring constant is a property of the spring and must be measured experimentally. The larger the value of k, the stiffer the spring. In equation form, Hooke's law can be written F = -kz. The minus sign indicates that the force is in the opposite direction to that of the spring's displacement from its equilibrium length and is "trying" to restore the spring to its equilibrium position. The magnitude of the force is given by F = kx, where x is the magnitude of the displacement. In Haiti, public…

Question 1 Not yet answered Marked out of 1.00 P Flag question A spring (k = 800 N/m) is placed in a %3D vertical position with its lower end supported by a horizontal surface (see Figure). The upper end is depressed 20 cm, and a 0.5-kg block is placed on the depressed spring. The system is then released from rest. How far above the point of release will the block rise? m K Select one: a. 2.8 m
For the system below, let k = 200 N/m, b = 20 N*s/m, and m = 0 kg. For the following cases, sketch the displacement graph over time and define the energy stored in the system at the beginning and at steady state. a. x(0) = 0; f(t) = 0 b. x(0) = 0.3m; f(t) = 0 C. x(0) = 0m; f(t) = 25 N m = 0 k ий 1+1 f(t) b
A block with a mass m = 2.5 kg is pushed into an ideal spring whose spring constant is k = 4520 N/m. The spring is compressed x = 0.066 m and released. After losing contact with the spring, the block slides a distance of d = 2.25 m across the floor before coming to rest. a. Write an expression for the coefficient of kinetic friction between the block and the floor using the symbols given in the problem statement and g (the acceleration due to gravity). (Do not neglect the work done by friction while the block is still in contact with the spring.)
