What was the speed of the bullet-bob

Reference no: EM13252062

Suppose a bullet of mass m = 6.77g is fired into a ballistic pendulum whose bob has a mass of M = 0.693kg .

If the bob rises to a height of 0.135m , what was the initial speed of the bullet?

What was the speed of the bullet-bob combination immediately after the collision takes place?
