We know that 20 m/s N is a vector quantity because N in the expression signifies the direction
<h3>What is a vector quantity?</h3>
This is a which have both magnitude and direction. Example include:
- Velocity
- Displacement
- Force
- Acceleration
- Moment
- Weight
<h3>How to determine whether 20 m/s N is a vector quantity</h3>
- 20 m/s indicates just the speed i.e magnitude
- 20 m/s N indicates the speed i.e magnitude why the N indicates the direction.
Thus, we can conclude that 20 m/s N is a vector quantity because it has both magnitude and direction.

2 positive, 1 negative .... net 1 positive per step
Answer:
Explanation:
We know that:
where 
is the initial energy, 
is the final energy and 
is the energy lost due to friction.
so:
Where M is the mass and V is the velocity of the runner, so:
