Question

In a lab, four balls have the same velocities but different masses.

A 4 column table with 4 rows. Column 1 is labeled Object with entries Ball A, Ball B, Ball C, Ball D. Column 2 is labeled Mass in kilograms with entries 1.0, 2.0, 5.0, 7.0. Column 3 is labeled velocity in meters per second with entries 2.2, 2.2, 2.2, 2.2. Column 4 is labeled Momentum in kilograms times meters per second with entries 2.2, 4.4, 11, 15.
If the mass of ball B triples, its new momentum is
kg • .

Answer 1

Mass becomes 6.0 kg, so p = mv = 6.0(2.2) = 13.2 kg·m/s.
