A simple pendulum makes 128 complete oscillations in 2.80 min at a location where g = 9.80 m/s2. Find the length of the pendulum.

Despite their crazy structure, human bones are surprisingly good!

The statement that best describes the object on the right is a bar magnet with its north pole on the left.

Ek₀ and ep₀ are initial kinetic and potential energies respectively.ek and ep are final kinetic and potential energies respectively.energy in the system is conserved.ek₀ + ep₀ = ek + epassume student is one some ground ground, so ep₀ = 0at the apex of student's swing, ek = 0ek₀ + 0 = 0+ epek₀ = epmv₀²/2 = mghmass cancels outv₀²/2 = ghh = v₀²/(2g)h = (3.5 m/s)²/(2 * 9.81 m/s²)h = 0.62 mhe will swing 0.62 m high (relative to where he was running before)

Do you have the diagram?
