Answer:
We can easily find out the beginning point of the line by using dot representation.
When it comes to position vector, it expresses the exact position of certain object from the starting point of the coordinate system.
The vector is a straight line that has a certain end which is fixed to its body.
The other end is linked with a moving point that tells an accurate position of that specific point.

Answer:
a) It will take you 16.94 min to climb the stairs.
b) The numbers of flights are 123 flights.
Explanation:
a) Let the energy consumption while climbing the stairs be 685 W in kcal/min is given by:
rate of energy consumption = (685 W)×[(0.01433kcal/min)/1 W]
= 9.81605 kcal/min
the time it takes to climb the stairs is given by:
t = E/P
= (166.0 kcal)/(9.8 kcal/min)
= 16.94 min
Therefore, it will take you 16.94 min to climb the stairs.
b) Given t is the time it takes to climb stairs and N is the number of stairs to climb per min, then the number of stairs is:
n = t×N
= (16.94)×(116)
= 1965 stairs
given the number of stairs each flight as N1, then the number of flights is given by:
flights = n/N1
= (1965)/(16)
= 123 flights
Therefore, the numbers of flights are 123 flights.
