A 0.02-kg bullet collides with a 5.75-kg pendulum. After the

Question

collision, the bullet remains embedded onto the pendulum and the pair swings up to a maximum height of 0.386m.

1. Find the total energy of the pair at the maximum height of 0.386 m.

2.What is the initial speed of the pair at the bottom before swinging? Note: energy is conserved from the bottom to the maximum height.

3.What is the initial speed of the bullet? Note: In the collision of bullet and pendulum, momentum is conserved.
