Question

A 4 column table with 3 rows. The first column is unlabeled with entries, Object 1, Object 2, Object 1 + Object 2. The second column is labeled m in kilograms with entries 2.0, 6.0, 8.0. The third column is labeled v in meters per second with entries 4.0, 0 , 1.0. The last column is labeled p in kilogram meters per second with no entries.
A set of data is collected for objects in an inelastic collision, as recorded in the table.

To identify the momentum of Object 1, you must multiply
and
to find momentum.

Object 1 had a momentum of
kg ∙ m/s before the collision.

Object 2 had a momentum of
kg ∙ m/s before the collision.

The combined mass after the collision had a total momentum of
.

Answer 1

To identify the momentum of Object 1, you must multiply mass and velocity (m × v).

Object 1 had a momentum of 2.0 kg × 4.0 m/s = 8.0 kg·m/s before the collision.

Object 2 had a momentum of 6.0 kg × 0 m/s = 0.0 kg·m/s before the collision.

The combined mass after the collision had a total momentum of 8.0 kg·m/s (8.0 kg × 1.0 m/s).
