A simple pendulum with a length of 1.93 m and a mass of 6.54 kg is given an initial speed of 2.46 m/s at its equilibrium position.
(a) Assuming it undergoes simple harmonic motion, determine its period.
(b) Determine its total energy.
(c) Determine its maximum angular displacement. (For large v, and/or small l, the small angle approximation may not be good enough here.)
A skier is initially stationary, but then accelerates at2.4 m/s2 down a hill that isinclined 23° below the horizontal. How far horizontally and vertically has the skier traveled in6 s?
