5. Keeping in mind that the moment of inertia of a solid sphere is / = MR2, consider a solid sphere with radius 4 cm rolling without slipping along the landscape shown. If the ball at the initial position at left has a speed of 3 m/s, what is its speed at the top of the 0.5 m hill? 1.0 m 3 m's 0.5 m 0m

The solid line below is a graph of pressure vs. position for a harmonic
pressure wave in air (a sound wave) with a speed of 330 m/s, an amplitude of
60 Pa, and a frequency of 400 Hz. The dotted line is the graph of a 2nd sound
wave, also with a speed of 330 m/s. What is the
A) amplitude, B) angular frequency, and C) wavenumber of this 2nd wave?

A mass attached to a spring sliding on a
frictionless surface is traveling right at 4 m/s
when it reaches the spring's x = 0 equilibrium
point at t = 0. A bit later, when it has stretched
the spring 1 cm, it has slowed to 3 m/s. The
simple harmonic motion of this mass is described
by the equation x(t) = xm cos(wt + p).
