In the laboratory, a student studies a pendulum by graphing the angle 0 that the string makes with the vertical as a function of time t, obtaining the graph shown in the figure (Figure 1). Figure 1 of 1 0 (degree) 4 1.0 2.0 (s) 3.0 -2 -4 -6 Part A What is the period of the pendulum's motion? Express your answer to two significant figures and include the appropriate units. HA 1 ? T = Value Units Part B What is the frequency of the pendulum's motion? Express your answer to two significant figures and include the appropriate units. H H f = Value Units Part C What is angular frequency of the pendulum's motion? Express your answer in radians per second to two significant figures. W = rad/s Part D What is the amplitude of the pendulum's motion? Express your answer in degrees to one significant figure. ? Omax = Part E How long is the pendulum? Express your answer to two significant figures and include the appropriate units. HA 1] ? L = Value Units Part F Is it possible to determine the mass of the bob? yes O no
