Answer:
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.
