Q. A 8.0 x15 swimming pool slopes linearly from a 1 depth at one end to a 3.70 depth at the other. What is the mass of water in the pool?
Q. A 2.10 kg object attached to a spring moves without friction (b = 0) and is driven by an external force given by the expression F = 3.20 sin (2πt), where F is in newtons and t is in seconds. The force constant of the spring is 22.0 N/m.
(1) Find the resonance angular frequency of system.
(2) Find the angular frequency of the driven system.
(3) Find the amplitude of the motion.
