Immediately upon reaching its lowest point, a falling pendulum bob has its greatest amount of kinetic energy, which is less than the initial amount of potential energy.
remember the law of energy there cannot be any more since it is using the potential energy to move
the net torque about the point (-1 m, 1 m) is 4 N-m.
The resultant force acting on the object is calculated as
R^2=(-5+3)^2+2^2=2.82 N
Distance of the point from the resultant force
d^2=(-1)^2+1^2=1.414
The net torque acting on the point (-1 m, 1 m) is
T=2.82×1.41=3.98 N-m
Many people are in favor of the dam. Hydroelectric power is not as polluting
as other forms of electrical generation. The country is growing quickly, and
its economy is growing. The country must be able to produce more electricity
to meet everyone's needs. However, those opposed say the dams will force
many out of their homes. It will destroy an important wilderness area, and may
damage ecosystems - especially river or fjord ecosystems in Patagonia, since
silt won't be carried down rivers. Many also say that the project helps the
copper mining industry, and they believe that this project will benefit
businesses, not the people of Chile
There is so much force coming at once and adrenaline so you don't feel it
Answer:
PE = M g H gravitational potential energy
KE - 1/2 M V^2 kinetic energy
PE = KE kinetic energy equal to initial gravitational energy
