- Review. A light spring has unstressed length 15.5 cm. It is described by Hookes law with spring constant 4.30 N/m. One end of the horizontal spring is held on a fixed vertical axle, and the other end is attached to a puck of mass m that can mow without friction over a horizontal surface. The puck is set into motion in a circle with a period of 1.30 s. (a) Find the extension of the spring x as it depends on m. Evaluate x for (b) m = 0.070 0 kg. (c) m = 0.140 kg, (d) m = 0.180 kg, and (e) m = 0.190 kg. (f) Describe the pattern of variation of x as it depends on m.arrow_forwardA small body of mass m resting on a smooth horizontal plane is attached by threads to a point P (see figure) and, by means of a weightless pulley, to a hanging weight possessing the same mass m.Besides, the small body is also attached to the ceiling by means of a light non-deformed vertical spring of length L0 = 50 cm and spring constant k = 5mg/L0. The thread connecting the small body and point P having been burned, the small body starts moving. Find its velocity at the moment when it is breaking off the plane.arrow_forwardA 0.35 kg mass is held against a compressed spring with a spring constant of 89 N/m. The mass is initially at rest upon a horizontal surface and the spring force is directed parallel to the plane of the surface. If the coefficient of kinetic friction is 0.86, with what speed does the mass leave contact with the spring if the spring is initially compressed by 0.232 m?arrow_forward
- ( ANSWER e,f, and g ), a is given ) You have two equal masses m1 and m2 and a spring with a spring constant k. The mass m1 is connected to the spring and placed on a frictionless horizontal surface at the relaxed position of the spring. You then hang mass m2, connected to mass m1 by a massless cord, over a pulley at the edge of the horizontal surface. When the entire system comes to rest in the equilibrium position, the spring is stretched an amount d1 as shown in figure (a). You are given the following information. ( ANSWER E,F, and G ), A is given ) The mass m1 = m2 = 0.500 kg.The spring constant k = 290 N/m. (a) Determine the amount the spring is stretched (d1) when m2 is attached to m1. d1 = 0.01689 m Correct: Your answer is correct. You now pull the mass m2 down a distance d2 = 4 cm and release it from rest, as shown in figure (b). Determine the following as the two masses travel the distance d2 back to their equilibrium positions.
