Obtain an expression for the ratio of the average kinetic energy k to the average total energy e of the oscillator in terms of the dimensionless quantity ωo/ω. sketch this expression over an appropriate range of ω. for what value of ω are the average values of the kinetic and potential energies equal?

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
