A(n) 10.1 g bullet is fired into a(n) 2.41 kg ballistic pendulum and becomes embedded in it. The acceleration of gravity is 9.8 m/s 2 . If the pendulum rises a vertical distance of 3.12 cm, calculate the initial speed of the bullet

Explanation:

The motion of ballistic pendulum is modelled by the appropriate use of the Principle of Energy Conservation:

The final velocity of the system formed by the ballistic pendulum and the bullet is:

Initial velocity of the bullet can be calculated from the expression derived of the Principle of Momentum:

tube or goog with be a great resource to with that question

overcharge is the right answer system
