1.The range from high to low tide in a particular bay is found to be d meters. The variation in height of the water acts as simple harmonic motion with a period of 12.5 hours. How long does it take for the tide to subside (go down) a distance of 0.35d from its maximum level?

Your answer should be in hours, but enter only the numerical part in the box.

2. A simple harmonic oscillator is made up of a mass-spring system, with mass of 2.4 kg and a spring constant k = 112 N/m. At time t=1.51 s, the position and velocity of the block are x = 0.12 m and v = 3.137 m/s. What is the velocity of the oscillation at t=0? Be sure to include the minus sign for negative velocity.

Your answer should be in m/s, but enter only the numerical part in the box.
