Four billiards balls, each of mass 0.5 kg, all are traveling in the same direction on a billiard table, with speeds of 2 m/s, 4 m/s, 8 m/s, and 10 m/s. What is the linear momentum of this system?
Step 1: Given data
Mass of four balls =
Speed of
Step 2: Calculating the momentum of each ball
Linear momentum- A system's linear momentum is just the sum of its constituent parts' linear momentum.
The momentum in terms of the velocity and mass of the ball is,
Momentum for
Momentum for
Momentum for
Momentum for
Step 3: Calculating linear momentum of the system,
We will add an equation so that we get net linear momentum.
Hence, the net linear momentum of this system is .
