Apendulum consists of a 5.7 kg ball suspended by a 1.8 m length of string with negligible mass and is initially at rest. a 4.8 g bullet travelling at 605 m/s is fired horizontally into the ball and is lodged there. the ball and bullet rise together to a maximum height of h. find h (in cm) a: 0.317 b: 0.422 c: 0.561 d: 0.747 e: 0.993 f: 1.32 g: 1.76 h: 2.34 tries 0/20 how long does it take from the moment of impact for the ball to first reach its maximum height? (in s)
