    ____ 1. A simple pendulum, 2.0 m in length, is released with a push when the support string is at an angle
    of 25 deegree from the vertical. If the initial speed of the suspended mass is 1.2 m/s when at the release
    point, what is its speed at the bottom of the swing? (g = 9.8 m/s2)
    a. 2.3 m/s
    b. 2.6 m/s
    c. 2.0 m/s
    d. 1.8 m/s
    e. 0.5 m/s

    ____ 2. A Hooke's law spring is mounted horizontally over a frictionless surface. The spring is then
    compressed a distance d and is used to launch a mass m along the frictionless surface. What
    compression of the spring would result in the mass attaining double the speed received in the
    above situation?
    a. 1.41 d
    b. 1.73 d
    c. 2.00 d
    d. 4.00 d
    e. 5.35 d
