Call the applied force 'A'. (Clever ?)
The forces on the cart are 'A' forward and 15 N backward.
The net force on the art is (A-15) forward.
F = m a
Net forward force = (mass of the cart) x (its forward acceleration)
(A - 15) = (16.5) x (2.31)
A - 15 = 38.115
Add 15 to each side:
<u>A = 53.115 newtons</u>
Answer
given,
initial speed,u = 0 m/s
final speed,v = 24.8 m/s
time, t= 5.9 s
a) acceleration,
a = 4.20 m/s²
b) distance to travel in that time
using equation of motion
v² = u² + 2 as
24.8² = 0² + 2 x 4.20 x s
8.4 s = 615.04
s = 73.22 m
the motorcycle will travel 73.22 m
According to research, none of these men were executed for believing that Earth revolves around the sun. Nicolaus Copernicus was the first to believe in the heliocentric view of the current solar system, but he was not killed for that view, but he died of natural means. Galileo Galilei was punished because of the heliocentric view but was only put under house arrest, and not killed. Giordano Bruno was indeed burned at stake, but it was not for his view on heliocentrism.
Answer:
Police powers are the fundamental ability of a government to enact laws to coerce its citizenry for the public good, although the term eludes an exact definition. The term does not directly relate to the common connotation of police as officers charged with maintaining public order, but rather to broad governmental regulatory power. Berman v. Parker, a 1954 U.S. Supreme Court case, stated that “public safety, public health, morality, peace and quiet, law and order. . . are some of the more conspicuous examples of the traditional application of the police power”; while recognizing that “an attempt to define police powers reach or trace its outer limits is fruitless.”
