Question
Suppose a bullet of mass m = 6.96 g is fired into a ballistic pendulum whose bob has a mass of M = 0.677 kg.
(a) If the bob rises to a height of 0.141 m, what was the initial speed of the bullet?
I got .042 km/s; but its wrong.
(b) What was the speed of the bullet-bob combination immediately after the collision takes place?
I have no idea how to find this.
