<h3>2.<u> Answer;</u></h3>
Momentum
<h3><u>Explanation;</u></h3>
- <em><u>Momentum refers to mass in motion, which means that objects that have mass and are in motion, will posses momentum, that is, they have their mass in motion. </u></em>
- <em><u>Momentum is given as the product of velocity of an object and its mass. Therefore, the amount of momentum possessed by a moving object or body is the product of mass and velocity. That is; p = m × v</u></em>
- From the equation, momentum is directly proportional to both mass and velocity.
<h3>3. <u>Answer;</u></h3>
Momentum
<h3><u>Explanation;</u></h3>
- <em><u>During collision, a force acts upon a body for a given amount of time change the velocity of an object. Product of force and time is called impulse</u></em>. The product of mass and velocity change is the change in momentum.
- <em><u>During collision the momentum change experienced by one object is equal in magnitude and opposite in direction to the momentum change experienced by the other object in collision.</u></em>
- That is; M1V1 =M2V2
<h3>4. <u>Answer; </u></h3>
= 250 kgm/s
<h3><u>Solution and explanation;</u></h3>
- <em><u>Momentum is given as the product of velocity of an object and its mass. </u></em>Therefore, the amount of momentum possessed by a moving object or body is the product of mass and velocity.
- That is; p = m × v
- mass = 50 kg, velocity = 5 m/s ; thus momentum will be;
- p = 50 × 5 = 250 kgm/s
Therefore, <em><u>momentum of the ice skater will be; 250 kgm/s</u></em>
c) so they could benefit from using the most accurate measurement system

Since you didn't tell us the choices, I can pick anything I like.
The one that always does it for me is " foaming brine " .
A closed circle means the number is included and an open circle means its not.
