1. The problem statement, all variables and given/known data A simple pendulum, 2.0 m in length, is released from rest when the support string is at an angle of 25° from the vertical. What is the speed of the suspended mass at the bottom of the swing? 2. Relevant equations R2= X2 + Y2 3. The attempt at a solution I know the answer is 1.9ms-1 but i keep getting 1.8126ms-1 which is 2.cos(25) what am i doing wrong?
