Amass is suspended from a cable to form a pendulum. when the mass is displaced from its resting position and allowed to swing, the displacement of the mass relative to its resting position is periodic. what is the general form of a trigonometric function with amplitude and frequency that could model the displacement of the mass relative to its resting position as a function of the time after passing through the resting position?

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
