A spring oscillator is designed with a mass of 0.130 kg. It operates while immersed in a damping fluid, selected so that the oscillation amplitude will decrease to 1.00% of its initial value in 6.69 s. Find the required damping constant for the system.
A 0.500-kg mass on a spring has velocity as a function of timegiven by vx(t) = (3.60cm/s) sin[(4.71s-1)t -?/2]. compute the force constant of the spring
Block A in Figure is given an initial velocity of 6 m/s up the incline. Declare of a block on a inclined plane.
