Shawn and his bike have a total mass of
50.9 kg. shawn rides his bike 0.88 km in
16.3 min at a constant velocity.
the acceleration of gravity is 9.8 m/s2.
what is shawn's kinetic energy?
answer in units of j.

Shawn's kinetic energy is 20.6 J

Explanation:

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

(v)=

=

= 0.899

Substituting the values we get kinetic energy (k) =

, k = 20.60 kg

as 1J = 1 kg

So, k = 20.60 kg = 20.6 J
