Let's consider the system given in Figure 2. The end of a flexible spring with spring constant k is attached to the wall and the other end to a block of mass m.

Could you help me with this question, please? If necessary, I can ask this in two questions. Consider a block of mass m attached to a spring with force constant k, as shown in the figure(Figure 1). The spring can be either stretched or compressed. The block slides on a frictionless horizontal surface, as shown. When the spring is relaxed, the block is located at x=0. If the block is pulled to the right a distance A and then released, A will be the amplitude of the resulting oscillations. Assume that the mechanical energy of the block-spring system remains unchanged in the subsequent motion of the block. Part G What is the period T ? Part H How much time t does the block take to travel from the point of maximum displacement to the opposite point of maximum displacement? Part I What distance d does the object cover during one period of oscillation? Part J What distance d does the object cover between the moments labeled K and N on the graph?

let's say we have a spr1ng that has a constant of k= 300 kn/m and this spring is attached to our incline at the top. the angle of this include is at the horizontal and we need to know that this incline has an angle of 30 degrees. now, after we have this problem, there is a projectile that has a mass of 1 kg that is pointing up the plane. the initial position of this projectile is d = 1.3 m and its from the end of a unc0mpressed spring. a. lets say the incline has no friction at all. lets just say. lets give a kinetic energy for the projectile and it is 15J. how much compressi0n will the spring receive? b. lets say we have a coef of fr1ction of 0.300 and the spring will have to compress 1.10 the instance the projectile stops.. in order for this to happen, what should be the initial speed of the projectile?
Physics students do an expriment to determine the coefficient of kinetic friction between a wooden object and the horizontal table it is on. This object has a mass of 1.6 kg. The students push it against a spring, which compresses the spring by 18cm. When released, the spring sends the object moving across the table and it stops 82 cm from where it was released. The spring constant is 200 N/m. Find the obeject-table coefficient of kinetic friction.
