Question: A = 1 , B = 1 6 and C = 7 A bullet of mass ( 7 . 5 + A ) g is

A=1, B=16 and C=7
A bullet of mass (7.5+ A) g is fired into a block of wood of mass (0.35+(B/100)) kg suspended by a (0.80+(C/10)) m long string. If the block swings up so the strings make an angle of 64.0 degrees from vertical, what was the initial speed of the bullet?
