Explain how the First Law of Thermodynamics (law of conservation of energy) is demonstrated by the Flash coming to a stop after running at 500 mph. How many NEWTONS of force would this require to stop him? What do you think would happen to the earth under his feet…or even to his shoes? Why?

hello

Explanation:

the first thing you want in a car that has been the

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
