What was David Berkowitz best known for? How did arson play a role in his past?
tankabanditka [31]
David Berkowitz, who became known as Son of Sam, went on a murderous rampage in New York City during the 1970s, taunting and insulting police, until they captured him. On August 10, 1977, 11 days after his last murder, David Berkowitz, known as Son of Sam, was arrested and later sentenced to six consecutive 25-years-to-life terms. Arson has evolved, since the 18th century, from a wrongful individual act into an effective means of collective violence, too. From 1750, the privatisation of common land in England limited peasants' access to resources such as firewood and game. Hope this helped!

What is kinetic energy and what is net force formula
Over [174]

Answer:

Here's the equation for net force: F = ma. The work done on the plane, which becomes its kinetic energy, equals the following: Net force F equals mass times acceleration. Assume that you're pushing in the same direction that the plane is going; in this case, cos 0 degrees = 1, so.

Explanation:

In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes

Hope this help also looking it up helps ;)
