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

Tripling the mass of Ball B to 6.0 kg and keeping its velocity at 2.2 m/s results in a new momentum of 13.2 kg·m/s.

If the mass of ball B triples, its new momentum can be calculated using the momentum formula, which is momentum (p) = mass (m) × velocity (v).

From the information provided, Ball B originally had a mass of 2.0 kilograms and a velocity of 2.2 meters per second, which gave it a momentum of 4.4 kg·m/s.

If the mass of Ball B triples, it becomes 6.0 kilograms. Keeping the velocity the same, the new momentum of Ball B is:

New momentum of Ball B = 6.0 kg × 2.2 m/s = 13.2 kg·m/s.
