The graphs in the table above apply to pendulum motion as well as the motion of a mass on a spring. A pendulum in a clock has a period of 2.0 seconds.

You pull the pendulum to the right-a positive displacement-and Jet it go; we call this time t = 0 s. At what time will the pendulum

(a) first be at its maximum negative dis placement,

(b) first have its maximum speed,

(c) first have its maximum positive velocity, and

(d) first have its maximum positive acceleration?

A. 0.5 s B. 1.0 s

c. 1.5 s D. 2.0 s
