Please answer this Physics question.

(i. A bullet with mass 10.0 g (mg) is red perfectly horizontally into a 1200 g wooden block (mw) hanging frOIn a 150-cm-long string. The bullet elnbeds itself into the block, and the block then swings out to an angle of 40.0\". (a) From the geometry provided, calculate how high the block swings ('yg)? (b) What is the velocity of the bullet and block system immediately after impact (1)1)? (c) What was the velocity of the bullet imInediately before embedding itself into the wood ((1%))3)
