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.
Low blood pressure. The person could faint and have an irregular heartbeat.
Latitude, elevation, ocean currents, topography, and prevailing winds. There's probably a few others but these are the most important.
The flow of electricity in a certain path is the circuit.
As momentum / time = force
so; time = 100÷15
so your answer is 6.7 !!
