A spring, hanging from the ceiling stretches 0.2 m when a 0.3 kg mass is gently suspended from it. The spring is then removed from the ceiling and placed in a horizontal direction with the same 0.3 kg mass resting on a frictionless surface. The mass is pulled such that the spring is stretched 0.15m from the equilibrium point and released from rest. Using 10 for gravity, determine: (a) The spring stiffness constant

A 1.350 kg air-track glider is attached to each end of the track by two coil springs. It takes a horizontal force of 0.500 N to displace the glider to a new equilibrium position, x= 0.290 m. Find the effective spring constant of the system. 1.72 N/m You are correct. Your receipt no. is 160-6527 The glider is now released from rest at x= 0.290 m. Find the maximum x-acceleration of the glider. Previous Tries 1.130rad/s Submit Answer You have entered that answer before Incompatible units.

A vertical spring-mass system has a 0.6kg weight attached to its end. You stretch the spring 0.4 m away from its equilibrium positon and when it oscillates up and down, it has a frequency of 2.5hz. (a) Calculate the Spring Constant (b) If you increase the distance that you stretch the spring-mass system, expalin how this would affect it's frequency. (c) At what distance from the spring-mass system's equilibrium position does it have the smallest acceleration? Explain your reasoning.

A 25 kg mass sliding on a horizontal frictionless floor at 10 m/s rams a spring that is attached to a vertical wall. a) Determine the spring constant when the maximum compression of the spring is 0.453 meters? b) How much compression does the spring have if the speed of the mass has decreased to 7.5 m/s? Show the fbd/figure, given and formula used.
