Problem 3.1:
Four billiard balls, each of mass .5 kg, all are traveling in the same direction
on a billiard table, with speeds 2 m/s, 4 m/s, 8 m/s and 10 m/s. What is the
linear momentum of this system?
[Solution]Problem 3.2:
A 60 kg man standing on a stationary 40 kg boat throws a .2 kg baseball with a
velocity of 50 m/s. With what speed does the boat move after the man throws the
ball? Assume no friction between the man and the boat.
[Solution]Problem 3.3:
A .05 kg bullet is fired at a velocity of 500 m/s, and embeds itself in a block
of mass 4 kg, initially at rest and on a frictionless surface. What is the final
velocity of the block?
[Solution]Problem 3.4:
An object at rest explodes into three pieces. Two, each of the same mass, fly
off in different directions with velocity 50 m/s and 100 m/s, respectively. A
third piece is also formed in the explosion, and has twice the mass of the first
two pieces. What is the magnitude and direction of its velocity?
[Solution]Problem 3.5:
A spaceship moving at 1000 m/s fires a missile of mass 1000 kg at a speed of
10000 m/s. What is the mass of the spaceship it slows down to a velocity of 910
m/s?
