Shawn and his bike have a total mass of
52.3 kg. shawn rides his bike 1.6 km in
17.4 min at a constant velocity.
the acceleration of gravity is 9.8 m/s
2
.
what is shawn’s kinetic energy?

Shawn's kinetic energy is 61.45 J.

Explanation:

Given;

Mass of the system is,

Displacement of the bike is,

Time taken is,

Let the constant velocity be .

For constant velocity, magnitude of velocity is given as distance by time.

Therefore,

Now, kinetic energy of a body is given as:

Here,

Therefore, Shawn's kinetic energy is 61.45 J.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
