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

R^{2}= X^{2}+ Y^{2}

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?
