# Question

(a) At what position is the magnitude of the force on a mass in a mass–spring system minimum: (1) x = 0, (2) x = – A, or (3) x = + A? Why?

(b) If m = 0.500 kg, k = 150 N/m, and A = 0.150 m, what are the magnitude of the force on the mass and the acceleration of the mass at, x = 0.050 m, and 0.150 m?

(b) If m = 0.500 kg, k = 150 N/m, and A = 0.150 m, what are the magnitude of the force on the mass and the acceleration of the mass at, x = 0.050 m, and 0.150 m?

(a) At what position is the speed of a mass in a mass–spring system maximum: (1) x = 0, (2) x = – A, or (3) x = + A? Why? (b) If m = 0.250 kg, k = 1000 N/m, and A = 0.10m for such a system, what is the mass’s maximum ...A 0.350-kg block moving vertically upward collides with a light vertical spring and compresses it 4.50 cm before coming to rest. If the spring constant is 50.0 N/m, what was the initial speed of the block? (Ignore energy ...If the frequency of a mass–spring system is 1.50 Hz and the mass on the spring is 5.00 kg, what is the spring constant? Show that the total energy of a mass–spring system in simple harmonic motion is given by ½ mw2A2. During an earthquake, the floor of an apartment building is measured to oscillate in approximately simple harmonic motion with a period of 1.95 seconds and an amplitude of 8.65 cm. Determine the maximum speed and ...Post your question
