2d and 2f answered please 3) The angle of pendulum from straight down will vary in a sinusoidal fashion as it swings. In Physicsyou will learn (if you haven't already) that for a frictionless pendulum, released k radians fromfeetvertical will be 0 (t)= k cos(t). gis gravitational acceleration, on Earth's surface ~32s2.For our problem the length is 20 inches, which will require conversion to be the L in the equation.We will use k = 0.15 radians.а.Find the angular frequency (w) of the oscillation.L = 20 in.e = 0.15 radb. Find the period in seconds.Find the time until (t) = 0. (ie when it is straight down)С.d. Plot one complete cycle of the waveform by hand. Be sure to label the amplitude and periodon the plot.e. Using a software tool, confirm your calculations and plot the function over one cycle.Confirm that it agrees with your hand plot.f.Suppose we had chosen to write the pendulum equation using a sine function instead of acosine. What phase offset would we have to add to get the same behavior?
