The ballistic pendulum is an apparatus used to measure the speed
of a fast-moving projectiles, such as the bullet. A bullet of mass
m1 = 12 gis fired into alarge block of wood of mass m2 = 6 kg
suspended from some light wires. The bullet embeds in the block in
the entire system swings to a maximum height of 3.50 m.
a. Derive an expression for the velocity of the bullet. (Hint:
Both concepts of conservation of energy and conservation of
momentum will be employed in this problem.)
b. What is the velocity of the bullet in m/s?
