Answer:
Explanation:
The time taken by the cyclist can be found by using the formula
v is the velocity
d is the distance
From the question we have
We have the final answer as
Hope this helps you
Average acceleration is the variation of velocity over a specified period of time :
Where:
being the initial velocity and the final velocity (according to the information given from the described graph)
Then:
The answer is 10%. just took the test. hope it helps!!
2.04m
PE=mgh
h= PE/mg
h= 40/2(9.82)
h=40/19.64
h=2.04
is the variation of velocity 
over a specified period of time 
:
being 
the initial velocity and 
the final velocity (according to the information given from the described graph)
