Answer:
at point F
Explanation:
To know the point in which the pendulum has the greatest potential energy you can assume that the zero reference of the gravitational energy (it is mandatory to define it) is at the bottom of the pendulum.
Then, when the pendulum reaches it maximum height in its motion the gravitational potential energy is
U = mgh
m: mass of the pendulum
g: gravitational constant
The greatest value is obtained when the pendulum reaches y=h
Furthermore, at this point the pendulum stops to come back in ts motion and then the speed is zero, and so, the kinetic energy (K=1/mv^2=0).
A) answer, at point F
Answer:
Sorry to say but where is the photo???
The positive effect of technology being used might be using sethescope or checking BP rate if it is good.
Explanation:
I think it’s contact I’m not sure
B is the correct answer.
A is incorrect because energy is neither created nor destroyed.
C is incorrect because kinetic energy would keep the ball rolling, so that would not make sense.
Answer:
Because work can be defined as force time distance, we can also use the following equation
Solution
P=power (w or ft-lbf/s)
F=force (N or lbf)
D=distance (m or ft)
T=time (sec)
One horsepower is equivalent to 550 ft-lbf/s and 745.7 watts.
