A 9 kg mass slides to the right on a surface having a coefficient of friction 0.37 as shown in the figure. The mass has a speed of 5 m/s when contact is made with a spring (of con- stant 107 N/m). The mass comes to rest after the spring has been compressed a distance d. The mass is then forced toward the left by the spring and continues to move in that direction beyond the unstretched position. Finally the mass comes to rest a distance D to the left of the unstretched spring. Find the distance D where the mass comes to rest. Answer in units of m
Consider a system of three noninteracting identical bosons that move in a common external one-dimensional harmonic potential. Find the energy levels and wave functions of the ground state
A 200 g block hangs from a spring with spring constant 10 N/m. At t=0 s the block is 23 cm below the equilibrium point and moving upward with the speed of 125 cm/s. What are block's oscillation frequency? What is the block's distance from equilibri..
What inductance must be connected to a 25 pF capacitor in the oscillator capable of generating 480 nm (i.e., visible) electromagnetic waves.
Suppose that the separation between two speakers A and B is 3.20 m and the speakers are vibrating in-phase. They are playing identical 121-Hz tones and the speed of sound is 343 m/s. An observer is seated at a position directly facing speaker B in..
