A bullet with mass 0.02 kg is fired at 300 m/s and embeds itself in a stationary 1 kg block. What is the impulse experienced by the block?
Options
A
6 N·s
B
3 N·s
C
60 N·s
D
300 N·s
Answer & Analysis
Answer
A
Analysis
To calculate the impulse experienced by the
block, we use the impulse-momentum theorem:
The change in momentum () is the
product of the mass of the block and its change in velocity. Since the block
was initially stationary, its final velocity is the same as the bullet's
velocity after the collision.
Given:
Mass of the bullet
Initial velocity of the bullet
