Question

A 1.30-kg wooden block rests on a table over a large hole as in the figure below. A 5.10-g bullet with an initial velocity v_i is fired upward into the bottom of the block and remains in the block after the collision. The block and bullet rise to a maximum height of 23.0 cm.

An illustration shows a large wooden block of mass M resting on the center of a table that has a large gap—smaller in width than the block—at the center. A bullet of mass m is moving up toward this gap, and an upward arrow beside the bullet is labeled vector v_i.

(a) Describe how you would find the initial velocity of the bullet using ideas you have learned in this chapter.

(b) Calculate the initial velocity of the bullet from the information provided. (Let up be the positive direction.)
