A simple pendulum, 2.0 m in length, is released with a push when the support string is at an angle of 25 from the vertical. If the initial speed of the suspended mass is 2.0 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
  c. 2.8 m/s
  b. 2.6 m/s
  d. 0.5 m/s

Question 2
