Question

using mass and velocity to determine total momentum
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.

Explanation:

Step1: Recall momentum formula

The formula for momentum is $p = m\times v$, where $p$ is momentum, $m$ is mass and $v$ is velocity.

Step2: Calculate momentum of Object 1 before collision

For Object 1, $m = 2.0$ kg and $v=4.0$ m/s. So $p_1=m_1\times v_1 = 2.0\times4.0=8.0$ kg·m/s.

Step3: Calculate momentum of Object 2 before collision

For Object 2, $m = 6.0$ kg and $v = 0$ m/s. So $p_2=m_2\times v_2=6.0\times0 = 0$ kg·m/s.

Step4: Calculate total momentum after collision

For the combined mass (Object 1 + Object 2), $m = 8.0$ kg and $v = 1.0$ m/s. So $p=m\times v=8.0\times1.0 = 8.0$ kg·m/s.

Answer:

To identify the momentum of Object 1, you must multiply mass and velocity to find momentum.
Object 1 had a momentum of 8.0 kg·m/s before the collision.
Object 2 had a momentum of 0 kg·m/s before the collision.
The combined mass after the collision had a total momentum of 8.0 kg·m/s.
