A spring hanging from a hook has a relaxed length of 8.1 cm with no mass attached to it. When a 0.41 kg mass is hung from the spring the spring stretches to a new equilibrium length of 12 cm. The mass is then pulled downward an additional 5.8 cm from the equilibrium position and released from rest. How fast (in m/s) is the mass moving when it first passes through the original equilibrium position of the spring (the relaxed...

1. (100 points) On Earth, a mass m is attached to a vertically-hanging spring with a spring stiffness k and a relaxed length of Lo. You grab the mass and throw it downward. At the instant you release the mass, the spring's length is Lo s and the mass is moving downward with speed vo. Determine the new velocity and new net force acting on the mass T seconds after leaving your hand.

A horizontal spring with stiffness 0.66N/m has a relaxed length of 0.182m. A mass of 0.026kg is attached and you stretch the spring to a total length of 0.384m. The mass is then released from rest. What is the speed of the mass at the moment when the spring returns to its relaxed length of 0.182m? v= Submit Answer Tries 0/99

A 3.50 kg mass is attached to a spring and set into motion horizontally along a frictionless track. At time t = 0.00 s, the mass passes through the equilibrium position (x = 0.00 m) moving to the left. At time t = 0.85 s, the mass reaches the left endpoint (x = - 0.16 m). a) Write an equation to describe the motion of the mass throughout time. [4] b) Find the spring constant, k. [2] c) Find the...

3) mm m To keep the mass from accelerating, a spring is attached with spring constant k = 150 N/m. What is the coefficient of static friction if the spring must extend at least X - 15 cm from its unstretched length to keep the block from moving down the plane? Submit mi The spring is replaced with a massless rope that pulls horizontally to prevent the block from moving. What is the tension in the rope? N Submit

A mass of 0.200kg is attached to a spring of length 0.500m and is placed on a horizontal frictionless surface. The mass is then pulled so that the spring now stretches to a total length of 0.550m. The mass is then given an initial speed of 5.00 m/s and the mass undergoes simple harmonic motion with a period of 0.200s. Find the spring constant (k) of the spring. Find the amplitude oscillation of the mass. Find the speed of the...

45. • A spring of unstretched length L and spring constant k is attached to a wall and an object of mass M resting on a fric- tionless surface (Figure 12-24). The object is pulled such that the spring is stretched a distance A then released. Let the +x direc- tion be to the right. (a) What is the position function x(t) for the object? Take x = 0 to be the position of the object when the spring is...

A block with mass 0.5 kg is connected by a spring of relaxed length 0.10 m to a post at the center of a low-friction table. You pull the block straight away from the post and release it, and you observe that the period of oscillation is 0.9 s. Next you stretch the spring to a length of 0.22 m and give the block an initial speed v perpendicular to the spring, choosing v so that the motion is a...
