Shawn's kinetic energy is 20.6 J
We know that kinetic energy is given by the formula
We are given mass(m) = 50.9kg and
distance ridden by bike = 0.88km which is equal to 880m and
time taken = 16.3 min which is equal to 16.3*60 seconds = 978seconds
Given velocity is constant which is
Substituting the values we get kinetic energy (k) =
, k = 20.60 kg
as 1J = 1 kg
So, k = 20.60 kg = 20.6 J
potential energy is directly proportional to height.
more height = more potential energy.
greatest increase in height = greatest increase in potential energy
where are the points with the greatest increase in height ?
has to be c-e or d-e .
