A simple harmonic oscillator consists of an 0.80 kg block attached to a spring ( k = 200 N/m). The block slides on a horizontal frictionless surface about the equilibrium point x = 0 with a total mechanical energy of 4.0 J. (a) What is the amplitude of the oscillation? (b) How many oscillations does the block complete in 10 s? (c) What is the maximum kinetic energy attained by the block? (d) What is the speed of the block at x = 0.15 m?

A glass flask whose volume is 1000.00 cm³ at 0.0°C is completely filled with mercury at this temperature. When flask
and mercury are warmed to 54.5 °C, 8.75 cm³ of mercury overflow.
Part A
If the coefficient of volume expansion of mercury is 18.0 × 10-5 K-1, compute the coefficient of volume expansion
of the glass.
