Expert Solution

Step 1: Question 1

Momentum is measured in units of kilogram meters per second (kg m/s). This unit reflects the product of mass (in kilograms) and velocity (in meters per second), which are the components of momentum.

Mathematically

p=mv

Where:

$Error converting from MathML to accessible text.$ is the momentum.
$Error converting from MathML to accessible text.$ is the mass of the object.
$Error converting from MathML to accessible text.$ is the velocity of the object.

The unit for momentum is derived from this formula, which is kilogram meters per second (kg m/s).
